Question

HELP PLEASE IM STRUGGLING

Answer 1

Answer:

121°

Step-by-step explanation:

Since we are working with a parallelogram, A and C will have the same angle measure and B and D will as well. We can form an equation and solve for x.

9x - 5 = 10x - 19

~Add 5 to both sides

9x = 10x - 14

~Subtract 10x to both sides

-x = -14

~Divide -1 to both sides

x = 14

Find angle B with what we found for x.

9x - 5

9(14) - 5

126 - 5

121

Best of Luck!
