Question

He measure of ∠DBE is (0.3x−22)° and the measure of ∠CBE is (0.1x - 51)

Answer 1

x = 415

Explanation:

(0.3x - 25) + (0.1x - 51) = 90°

0.3x - 25 + 0.1x - 51 = 90

0.4x - 76 = 90

+ 76 + 76

0.4x = 166

÷0.4 ÷0.4

x = 415

The equation is a right angle so it's equal to 90°

I hope this helps!
