Question

FInd the value of x such that l ⊥ m.

A) 46

B) 48

C) 16

D) 10.7

Answer 1

x = 16°

Explanation:

It is 90° angle so their sum must be 90°( complement) .

3x + 5° + 37° = 90°

3x + 42° = 90° ... simplify the like term

3x = 90° - 42°

3x = 48°

3x/3 = 48°/3

x = 16°

So the answer is C, 16

Answer 2

C) 16

Explanation:

(3x + 5) + 37 = 90

3x = 90 - 5 - 37

3x = 48

x = 48/3 = 16
