Question

21 m_GFE - 7x + 7. m. NFE - 22º.and mZGFN = 5x + 5. Find .x.7x+7 45812x+10= 22iar 22-12

Answer 1

angle GFE=7x+7

angle NFE=22

angle GFN=5x+5

angle GFN + angle NFE= angle GFE

5x+5+22=7x+7

in one side the terms with x and in the other side the term with out x

5x-7x=7-22-5

-2x=-20

x=-20/-2

x=10

the correct answer is A
