WILL GIVE BRAINLIEST!! In this triangle, what is the value of x? enter your answer, rounded to the nearest tenth, in the box.
x = 56.5 and rounded to the nearest tenth is still gonna be 56.5 but to the nearest TENS is 60 (Please give brainliest!!)
Step-by-step explanation:
His is a right triangle so you can use SOH CAH TOA :
Sine = opposite/ hypotenuse
Cosine= adjacent/ hypotenuse
Tangent = opposite/ adjacent
here you have the hypotenuse and are looking to solve for the adjacent side to angle measure 28
so you can set this up like this: cos(28)= x/64
now multiply both sides by 64 and you'll get x = 56.5 just make sure your calculator is in degrees not radians

43+(-56) minus 78
-78 minus 65
-19 minus 4
-16 + 9
71 + (-18)
Answer:
Step-by-step explanation:
1. 43+(-56) - 78
43 - 56 - 78 = -91
2. -78 - 65 = -143
3. -19 - 4 = -23
4. -16 + 9 = -7
5. 71 + (-18)
71 - 18 = 53
Hope this helps!
Answer:
Step-by-step explanation:
43+(-56)minus 78= negative 91
43+-56= - 13 13-78= negative 91
-78 subtract 65=143 because when your in negatives it is opposite so when you subtract it is addition so what is -30 add 50=20. So what is -78 subtract 65=143
-19 subtract 4 =-23 because like I said in negatives it's opposite.
-16+9=7.
And last 71 + -18=53 because it is subtracting 18 since it is negatives.
Hope it helps :)

All the square root term are equal then they can be added. Then the length of piping is needed in all is 98√6.
What is the length?It is the measure of distance between the two points is called a length. It is a scalar quantity.
A builder needs three pipes of different lengths.
The pipes are 6√96 feet long, 12√150 feet long, and 2√294 feet long.
The length of pipes can be written as
[tex]6\sqrt{96} = 6 \sqrt{2*2*2*2*2*3} = 24\sqrt6[/tex]
[tex]12\sqrt{150} = 12 \sqrt{5*5*6} = 60\sqrt6[/tex]

2x+5y=-11
-8x-5y= -1
Answer:
x = 2 , y = -3
Step-by-step explanation:
by elimination method
+5y in equation 1 cancel -5y in equation 2
2x - 8x = -11 - 1
-6x = -12
divide both sides by - 6
- 6x/ -6 = -12/-6
x = 2
substitute x = 2 into equation ii
- 8 (2) - 5y = - 1
- 16 - 5y = - 1
collect like terms
- 5y = -1 + 16
- 5y = 15
divide both sides by -5y
-5y/-5y = 15/-5y
y = - 3

Radio direction finders are placed at points A and B, which are 4.44 mi apart on an east-west line, with A west of B. The transmitter has bearings 39.3 degrees from A and 313.9 degrees from B. Find the distance from A.
Answer:
3.09 miles
Step-by-step explanation:
Given one distance and two angles, we will need to use the Law of Sines. For this, we need to know the internal angles of the triangle formed by the various bearing lines.
The angle between the bearings of A and B from the transmitter will be the difference of the reverse of the given bearings.
A from T = 39.3° +180° = 219.3°
B from T = 313.9° -180° = 133.9°
Then the angle at T between receivers is ...
219.3° -133.9° = 85.4°
The angle between A and T as measured at B will be ...
313.9° -270° = 43.9°
These angles and length AB can be used with the Law of Sines to find AT:
AT/sin(B) = AB/sin(T)
AT = AB(sin(B)/sin(T)) = (4.44 mi)·sin(43.9°)/sin(85.4°)
AT ≈ 3.09 mi
The distance of the transmitter from A is about 3.09 miles.

An angle measures 36° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
Measure of each angle is 108 and 72 degrees.
Step-by-step explanation:
Let's the angle be "n"
Supplementary angle = 180 °
n- (180-x) = 36
n - 180 + n = 36
Combine like terms
n - 180 + n = 36
2n - 180 = 36
Add 180 to both sides of the equation
2n - 180+180 = 36+180
Simplify
2n = 216
Divide both sides of the equation by the same term
2n/2 = 216/2
Simplify
n = 108
2n = 216
Measure of each angle
1st = 108
2nd = 180-108 = 72

At a certain restaurant, 8 sandwiches and 10 burritos will cost $123.40. In addition, 5 sandwiches
and 9 burritos cost $97.20. Assuming that we are talking about the same sandwiches and burritos,
what is the cost of 1 sandwich? What is the cost of 1 burrito? Let x represent the cost of a
sandwich and y represent the cost of a burrito
Equation #1:
Equation #2:
Cost of 1 burrito:
Cost of 1 sandwich: $
Answer:
Equation 1: 8x + 10y = 123.4
Equation 2: 5x + 9y = 97.2
cost of a burrito = $7.30
cost of a sandwich = $6.30
Step-by-step explanation:
Let x = cost of a sandwich
Let y = cost of a burrito
Equation 1: 8x + 10y = 123.4
Equation 2: 5x + 9y = 97.2
Rewrite equation 1 to make y the subject, then substitute into equation 2 and solve for x:
8x + 10y = 123.4
⇒ 10y = 123.4 - 8x
⇒ y = 12.34 - 0.8x
5x + 9(12.34 - 0.8x) = 97.2
⇒ 5x + 111.06 - 7.2x = 97.2
⇒ 13.86 = 2.2x
⇒ x = 6.3
So cost of a sandwich = $6.30
Substituting x = 6.3 into equation 2 and solving for y:
5(6.3) + 9y = 97.2
⇒ 31.5 + 9y = 97.2
⇒ 9y = 65.7
⇒ y = 7.3
So cost of a burrito = $7.30
Answer:
8x + 10y = 123.40
5x + 9y = 97.20
OR
40x + 50y = 617
-40x - 72y = -777.6
x = $6.30
y = $7.30
Step-by-step explanation:
we can write this system of equations:
8x + 10y = 123.40
5x + 9y = 97.20
using the 'elimination method', we can multiply the first equation by 5 and the second equation by -8 to get:
5(8x + 10y) = 123.4(5)
40x + 50y = 617
-8(5x + 9y) = 97.2(-8)
-40x - 72y = -777.6
now we can add the new equations and solve for 'y':
40x + 50y = 617
-40x - 72y = -777.6
-22y = -160.6
y = 7.30
now we can substitute 7.3 for 'y' so we can solve for 'x':
8x + 10(7.3) = 123.4
8x + 73 = 123.4
8x = 50.4
x = 6.30
