# In Exercises 41 to 44, m ∠ 1 + m ∠ 2 = m ∠ A B C .Find x if m ∠ 1 = x , m ∠ 2 = 2 x + 3 , and m ∠ A B C = 72 ° . To determine

To find:

x for m2=x, m1=2x+3, and mABC=72°.

Explanation

Calculation:

Given,

m2=x,

m1=2x+3, and

mABC=72°.

m1+m2=mABC

Substitute;m2=x, m1=2x+3, and mABC=72° in the above relation,

2x+3+x=72
