54 degrees

Step-by-step explanation:

Since we know that the angles are supplementary, we can set them to be equal to 180 degrees when combined.

(7x+14) + (5x-26)=180

Drop the parentheses.

7x+14+5x-26=180

Combine like terms.

12x-12=180

Add 12 to both sides.

12x=192

Divide both sides by 12.

x=16

Since the question asks for the measure of angle B, we need to plug x back into that expression to find its measure.

5(16)-26

80-26

54

Angle B has a measure of 54 degrees.
