Answer:
48
Explanation:
ABC is a right triangle so the masure of ∠A = 90°
The sum of interior angles in a triangle is equal to 180 so we will write an equation accordingly to find the
missing angle:
90 + 2x + 14 + 4x - 26 = 180 add like terms
78 + 6x = 180 subtract 78 from both sides
6x = 102 divide both sides by 6
x = 17
Now replace x with 17 to calculate the measure of m∠B
2*17 + 14 = 48
