Question

What is the measure of angle B in degrees?

Answer 1

27° you have to end up at 180° so all of the numbers including 27 equal to 180

Answer 2

<B=119

Explanation:

Each line of the triangle is straight, meaning they add up to 180. Additionally, all the angles of the triangle add up to 180. Using that, you can find the measure of each angle.

For <C;

180-112=68

So <C=68

For <A;

180-51-68=61

So <A=61

To make sure that all these angles add up correctly;

51+68+61=180

For <B;

180-61=119

So <B=119
