Question

In the given figure, find the value of x and the complement of ∠x. (AB is perpendicular to BC)

Answer 1

Answer:

Step-by-step explanation:

According to u   AB⊥BC

or, $(x+20)+(2x+1)+(7x-11) = 90\\or, x+2x+7x+20+1-11 = 90\\or, 10x+10 = 90\\or, 10(x+1) = 90\\or, (x+1) = 9\\or, x = 8\\complement"x"=90-x = 90-8 = 82degrees$
