Question

XYZ is Shown Below


Determine the value of x.

Answer 1

10

Explanation:

8x + 5° + 3x + 25° + 4x = 180° (angle sum property of a triangle)

8x + 3x + 4x + 5° + 25° = 180°

15x + 30° = 180°

15x = 180° - 30°

15x = 150°

x = 150/15

x = 10°

hope it helps u!

Answer 2

x = 10

Explanation:

Every triangle has 180o. Just add the three angles together.

8x + 5 + 3x + 25 + 4x = 180 Combine the like terms.

15x + 30 = 180 Subtract 30 from both sides

15x = 180 - 30 Combine

15x = 150 Divide by 15

x = 150/15

x = 10
