Question

What is the measure of ∠b

Answer 1

26

Explanation:

triangle=180

81 + 73= 154

180 - 154= 26

Answer 2

∠m = 26

Explanation:

We know that the sum of the interior angles in a triangle is added up to 180°.

Accordingly,

∠81 + ∠73 + ∠m = 180°

Combine like terms.

∠154 + ∠m = 180°

Subtract 154 from both sides.

∠m = 26
