Question

In a parallelogram boat angle b is equal to 3x+8 and angle a is =4x-2

Answer 1

Answer:

$sum \: of \: angles \: = 18 0^{o} \\ 3x + 8 + 4x - 2 = {180}^{o} \\ 7x + 4 = 180 \\ 7x = 180 - 4 \\ 7x = 176 \\ x = \frac{176}{7} = 28 \\ then \: angles : - \\ 3x + 8 = 3 \times 28 + 8 \\ 84 + 8 = 92 \\ 4x - 2 = 4 \times 28 - 2 \\ 72 - 2 = 70$
