Question

Find x and complement of x​

Answer 1

Answer:

x = 8

complement of x = 82°

Step-by-step explanation:

AB is perpendicular to BC

so angle ABC is 90°

x+20 + 2x+1 + 7x-11 = 90

10x + 10 = 90

10x = 80

x = 80/10 = 8

complement of x = 90 - 8 = 82

Answer 2

AB is perpendicular to BC

angle ABC is 90degree

x+20+2x+1+7x-11=90degree

10x+10=90 degree

10 (x+1)=90degree

x+1=90/10

x+1=9

x=8degree

complement angle means sum of 2 angles is 90 degree

complement angle of x is 82degree
