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
