Question

Find the measure of this missing angle?

Answer 1

B = 61°

C = 61°

Explanation:

The sum of all the angles is 360.

When the angles are formed with straight lines like shown the angles back to back are equivalent or equal.

So you can take 119 and add it by itself to get 238.

You then get 360 and subtract 238 which gets you 122.

Then divide 122 by two and you have the answer for both b and c which is 61.
