Question

∠A and ∠ B ∠B are complementary angles. If m ∠ A = ( 2 x + 18 ) ∘ ∠A=(2x+18) ∘ and m ∠ B = ( 6 x − 8 ) ∘ ∠B=(6x−8) ∘ , then find the measure of ∠ B ∠B

Answer 1

Explanation:

in complementary angles sum of two angles is always 90 degree .

2x+18+6x-8=90

8x+10=90

8x=90-10

x=80/8

x=10

angle B=6x-8

=6*10-8

=60-8

=52 degree

therefore angle B is 52 degree
