Question

There are two complementary angles; <5 and <6 . If m<5 = 39 , what equation can you write to solve for m<6

answers:

m<6 + 39 = 180

m<6 + 39 = 90

m<6 = 39

m<6 = 180 - 39

Answer 1

are you sure

Answer 2

Two angles , <1 and <2 , in a diagram are supplementary. If m<1 = 77 , what equation can you write to solve for m<2? Let m<2 = x.

answers:

x + 77 = 180

x = 77

x + 77 = 90

x = 90 - 77

Answer 3

There are angles whose measures add to 180. Their measures are : m<A = 67 , m<B = (2x + 20) and m<C = x. What is the measure of <B?

Answer 4

If there are two supplementary angles, <D and <E , where m<D = (4x + 8) and m<E = (x + 17) , and <F is a vertical angle with <D , what is the measure of <F
