Question

4. LA and B form a linear pair. If MZA = (6x - 19) and mZB = (11x-22), find mZB. A. 59" B. 65 C. 115 D. 121 ​

Answer 1

<B =121

Explanation:

If the angles form a linear pair, they add to 180

6x-19 + 11x-22 = 180

Combine like terms

17x -41 = 180

Add 41 to each side

17x-41+41 = 180+41

17x = 221

Divide by 17

17x/17 =221/17

x =13

<b = 11x-22 = 11*13 -22 = 143-22 =121
