m/JHI =(2x+7)° and m/GHI = (8x - 2)° and m/JHG= 65°. Find m/JHI and m/GHI
Answers
The value of m/JHI and m/GHI is angle 19 and 46.
What is angle ?
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. Dihedral angles are these.
[tex]\begin{aligned}2 x+7+8 x-2 & =65 \\10 x+5 & =65 \\10 x & =60 \\x & =6\end{aligned}[/tex]
m/JHI =(2x+7) = (2* 6+7)=12+7=19.
m/GHI = (8x - 2)° = (8*6-2)=48-2=46

x =35. it is 105/3 if you read the equation it will make more sense.
Step-by-step explanation:
you have to flip the equation entirely
first you have to add 24 and 81 which will give you 105. then you have to divide by 3 and you get 35. then replay the equation with 35 replacing the x.
A boat can travel 40mph in still water. If it travels 126 miles with the current in the same length of time it travels 114 miles against the current, what is the speed of the current?
no links please
Answers
Answer:
rate of the current = 2 mph
Step-by-step explanation:
d = rt
Let c = rate of the current
Rate going downstream = c + 40
Time going downstream = 126/(40 + c)
Rate going up stream = 40 - c
Time going upstream = 114/(40 - c)
Since the times are equal, then
126/(40 + c) = 114/(40 - c)
126(40 - c) = 114(40 + c)
5040 - 126c = 4560 + 114c
240c = 480
c = 2 mph

у
270
350 ft
y = [? ]ft
Answers
Answer:
178.3
Step-by-step explanation:
Hello There!
We can find the value of y using trigonometry
These are the trigonometric ratios
Remember SOHCAHTOA
Sine = Opposite over Hypotenuse
Cosine = Adjacent over Hypotenuse
Tangent = Opposite over Adjacent
For the angle that has a measure of 27 degrees
we are given its adjacent angle and we need to find its opposite angle (y)
Adjacent and Opposite sides corresponds with the trigonometric ratio Tangent so we are going to use the trigonometric ratio tan to solve for y
Now we set up an equation (remember tangent = opposite over adjacent)
[tex]tan(27)=\frac{y}{350}[/tex]
Now that we have created an equation we want to solve for y
What we want to do is isolate the variable using inverse operations
So basically we want to get rid of the 350
The opposite of division is multiplication so we multiply each side by 350 to get rid of it
[tex]tan(27)*350=350tan(27)\\\frac{y}{350} *350=y\\y=350tan(27)\\350tan(27)=178.3339073\\[/tex]
so we can conclude that y = 178.3339073
finally we want to round to the nearest tenth and we get that the answer is 178.3

Answer:
x = 0 , 5
Step-by-step explanation:
[tex]\frac{2x}{x-3}=\frac{3x}{x-2}[/tex]
Cross multiply,
2x* ( x - 2) = 3x *(x - 3)
2x*x - 2*2x = x*3x - 3*3x
2x² - 4x = 3x² - 9x
subtract 2x² from both sides
-4x = 3x² - 2x² - 9x {Combine like terms}
-4x = x² - 9x
Add 9x to both sides
-4x+ 9x = x²
x² = 5x
x² - 5x = 0
x(x - 5) = 0
x = 0 ; x - 5 = 0
x = 5

let 'x' be the speed of the car.
60 × 2/3 = 120/3 = 40
30 × 1/5 = 151/5
151/5 /40 = x / 60
151 / 200 = x / 60
