Question

In parallelogram ABCD angle A is (6 y+5)° and angle B is (10 y-1). Determine the

Answer 1

Answer:

<C = 71degrees

Step-by-step explanation:

The length of opposite side of a parallelogram is 180degrees, hence;

<A + <B = 180

6y+5 + 10y - 1 = 180

16y + 4 = 180

16y = 180 - 4

16y = 176

y = 176/16

y = 11

<A = <C = 6y+5

<C = 6(11)+5

<C = 66+5

<C = 71degrees

Hence the measure of C is 71degrees
