Answer:

155.9 = h

Step-by-step explanation:

Since it is an equilateral triangle, the angles are all 60 degrees

Call the angle on the bottom right theta

Theta = 60 degrees

The angle h makes with the base is 90 degrees so it is a right triangle

sin theta = opp/ hyp

sin 60 = h/ 180

Multiply each side by 180

180 sin 60 = h

155.8845727  = h

To the nearest tenth

155.9 = h

Find the slope of the line <br> Y=-3x - 4
Dimas [21]
Let y=0 to find the x-intercept(s).
0=−3x−4

Add 4 to both sides.
4=−3x

Divide both sides by -3
-4/3 =x (fraction)

Switch sides.
x=−4/3 (fraction)

Let x=0 to find the y-intercept(s).
y=−3×0−4

Simplify
y=−4
