Question

∠ABC and ∠DBC are complementary angles. If m∠ABC=6x+13 and m∠DBC=4x−3 what is the value of x?

i need help ASAP!!

Answer 1

Answer: -8

Complementary angles are equal to 90 degrees.

angleABC=angleDBC

6x+13=4x-3

get x alone

2x+13=-3

subtract 13 from both sides

2x=-16

divide by 2 on both sides

x=-8
