The area of triangle IJK is 999.8 square centimeters
The given parameters are:
[tex]\angle I = 120^o[/tex]
[tex]\angle J = 59^o[/tex]
[tex]i = 340cm[/tex]
Start by calculating the length of side j using the following sine ratio
[tex]\frac{i}{\sin(I)} = \frac{j}{\sin(J)}[/tex]
Make j the subject of the formula
[tex]j = \sin(J) \times \frac{i}{\sin(I)}[/tex]
Substitute known values
[tex]j = \sin(59) \times \frac{340}{\sin(120)}[/tex]
Evaluate the expression
[tex]j = 337[/tex]
Next, calculate angle K using the following sum of angles formula
[tex]\angle I + \angle J + \angle K =180[/tex]
Substitute known values
[tex]120 + 59 + \angle K =180[/tex]
[tex]179 + \angle K =180[/tex]
Subtract 179 from both sides
[tex]\angle K =1[/tex]
The area of the triangle is:
[tex]Area = \frac{1}{2} ij \times \sin(K)[/tex]
So, we have:
[tex]Area = \frac{1}{2} \times 340 \times 337 \times \sin(1)[/tex]
Evaluate
[tex]Area = 999.8[/tex]
Hence, the area of triangle IJK is 999.8 square centimeters

What is the volume of this square pyramid?
Answer:
400m^3
Step-by-step explanation:
Answer: [tex]400m^{2}[/tex]
Step-by-step explanation:
In order to solve this square pyramid's volume, we use the formula:
V = 1/3(B)(h)
Now, we plug in what we know. Since it has a square base, the sides of the base are all the same:
1/3(10*10)(12)
Now we solve:
1/3(100)(12)
1/3(1200)

Part A: If Angle A and Angle B are vertical angles, what is value of x
A. 8
B. 10
C. 35
D. 28
Answer:
A. 8
Step-by-step explanation:
Since ∠A and ∠B are vertical, we can create the equation: 40 = 5x.
40 = 5x
There is only one other thing we need to do, and that's divide by 5.
40/5 = x
x = 8
The value of x in this case is 8, which is A.

. Frosty Snacks sells ice cream in a cylindrical cup and in cones.
The small cup of ice cream has a height of 4 inches and a radius
of 2 inches. The small cone has a height of 6 inches and a
diameter of 5 inches. How much more ice cream will fit into a
small cup than a small cone? Use 3.14 for pi.
Answer:
10.99 in^3
Step-by-step explanation:
Steps to determining the answer
determine the volume of the cylinderdetermine the volume of the conefind the difference in volumesvolume of a cylinder = nr^2h
n = 3.14
r = radius
3.14 x 4 x 2² = 50.24 in³
Volume of a cone 1/3(nr^2h)
n = 22/7
r = radius
A radius is half of the diameter = 5/2 = 2.5 in
h = height
(1/3) x 3.14 x 2.5² x 6 = 39.25 in³
difference = 50.24 - 39.25 = 10.99 in³

Lila covered 55 ft squared of her back yard with 3/4 of a load of sod. She has 3 loads of sod in all. If she wants to cover all 250 ft squared of her yard, does she have enough sod?
Answer:
More sod is needed
Step-by-step explanation:
Well we know that 3/4 of a bag of sod covers 55 ft^2 then if we divide 55 by 3 we get 18.3333 we take that and multiply by 4 to get 73.333 or the amount one bag of sod can cover
73.333*3 cuz 3 bags of sod is 220 ft^2
She needs more sod
What is the measure of angle z in this picture?
Answer:

Angle 43 and angle z make a straight line, which is 180 degrees
43+z = 180
Subtract 43 from each side
43+z-43 = 180-43
z =137

If a cone has a height of 8 inches and a side measurement of 10 inches, what is the radius of its base?
Answer:
The radius of its base is 6 inches
Step-by-step explanation:
The radius of the base of a cone r , the slant height of the cone l and the height of the cone h forms a right triangle, with the slant height being the hypotenuse of the right triangle
Mathematically, since we have a right triangle, we can find the radius of the base by the use of Pythagoras’ theorem
According to Pythagoras’ theorem; the square of the hypotenuse equals the sum of the squares of the two other sides
Thus,
l^2 = r^2 + h^2
l = 10 inches
r = ?
h = 8 inches
10^2 = r^2 + 8^2
100 = r^2 + 64
r^2 = 100-64
r^2 = 36
r = √(36)
r = 6 inches
