Question

Write a list of steps that are needed to find the measure of 10 years ago

Answer 1

where is the diagram?

Answer 2

ok so we know that triangles always add up to 180 degrees correct?

Answer 3

so in order to find b we need to know the measure of the other two angles in the triangle

Answer 4

they already gave us that angle a is 72 degrees. to find the measure of angle c we take 180-113. does it make sense why you do that?

Answer 5

yes it does sorry it wasent letting me type

Answer 6

ok you're good. from that we get 67 degrees. so now that we know angles a and c we add them together and subtract them from 180

Answer 7

\[180-(67+72)\]

Answer 8

ok

Answer 9

this should give you 41 which is your answer

Answer 10

did all that make sense?

Answer 11

yes it did thank you so much kisses

Answer 12

yep no problem!
