Question

Find the measure of the missing angels.

Answer 1

B = 119°

C = 119°

Explanation:

• The value of back to back angles are the same when the lines are straight.
• Therefor there are two 61° they add together to make 122°
• You can then subtract 122 from 360 to get 238.
• Then take 238 and divide it by 2, to get your answer which is 119° for both.

Answer 2

'b' and 'c' = 119 degrees

Explanation:

Given that this is a basic intersection of straight lines, we can assume 'b' and 'c' are equal as well as the given angle and it's opposite. Given 61 degrees and and two straight lines we can just take 180 degrees - 61 degrees and we get 119 degrees, I solved for 'b', but this will give the same answer for 'c', as 'b' and 'c' are equal.
