Angle WXZ = 23°

Explanation:

Angle WXZ and angle YXZ are complementary angles.

Complementary angles sum up to 90 degrees

Angle WXZ = (2x + 1)°

Angle YXZ = (7x - 10)°

Angle WXZ + Angle YXZ = 90°

(2x + 1)° + (7x - 10)° = 90°

2x + 1 + 7x - 10 = 90

collect like terms:

2x + 7x + 1 - 10 = 90

9x - 9 = 90

add 9 to both sides:

9x - 9 + 9 = 90 + 9

9x = 99

divide both sides by 9:

9x/9 = 99/9

x = 11

Angle WXZ = (2x + 1)° = 2(11) + 1

Angle WXZ = 23°
