Solve for x in the diagram below.

x=75

Step-by-step explanation:

A triangle is 180° in total and the equation was (2x+30)° if you subtract 30 from 180 you get 150 if you divide that by 2 you get 75.

2(75) + 30° =180°

x = 35

Step-by-step explanation:

x = 35, because first you have to add all your like factors. Then you'd get 2x + 110 = 180, afterwards you'd subtract 110 from both sides. Then divide 2 on both sides. Leaving you with x = 35.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
