I dont under stand 0=

Answer 1

b = 90°

Explanation:

There are three angles indicated in this image: 244°, 23°, and m∠b and the sum of these three angles is equal to 360° because they make full angle.

So to find the measure of m∠b, we need to add all given angles:

244° + 23° + m∠b = 360°

• Add like terms.

267° + m∠b = 360°

• Subtract 267° from both sides to isolate b.

m∠b = 93°
