Answer 1

What do all the angles of a triangle add up to?

Answer 2

what do u think it is

Answer 3

It add u t0 180

Answer 4

good!

so that means

b + d + 45 = 180

We want to know the value of d, but first we have to find the value of b

Answer 5

angle b and 107 add up to 180 because they are supplementary

so what is b

107 + b = 180
b = 180 - 107

b = ?

Answer 6

once you find b, we can find d

Answer 7

73

Answer 8

ok good!

now we have

d + b + 45 = 180

and we said that b is 73

so we get

d + 73 + 45 = 180

let's simplify that, shall we?

what is 73 + 45 = ?

Answer 9

118

Answer 10

and subtract that from 180 and we'll have our answer

180 - 118 = ?
