Question

Solve for x, and angle c

Answer 1

9514 1404 393

Answer:

x = 12.75

∠C = 51.75°

Explanation:

The two marked angles are complementary, so ...

(5x -12) +(3x) = 90

8x = 102

x = 102/8

x = 12.75

__

C = (5x -12)° = (5(12.75) -12)°

∠C = 51.75°

__

Check

E = 3x = 38.25, then C+E = 51.75 +38.25 = 90 . . . . as it should
