What is the value of x? enter your answer in the box. x = !

x = 25

The 3 angles are marked as equal , indicated by the arc at each angle.

Thus Δ ABC is equilateral with all 3 sides equal

Equate any 2 sides to solve for x

4x - 30 = 3x - 5 ( subtract 3x from both sides )

x - 30 = - 5 ( add 30 to both sides )

x = 25

As a check :

4x - 30 = ( 4 × 25 ) - 30 = 100 - 30 = 70

3x - 5 = ( 3 × 25 ) - 5 = 75 - 5 = 70

2x + 20 = ( 2 × 25 ) + 20 = 50 + 20 = 70

All 3 sides are equal for x = 25

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
