Answer:

m<BAD = 67

Step-by-step explanation:

The given figure is a parallelogram. Consecutive angles in a parallelogram are supplementary, meaning that their angle measures sum up to 180 degrees. Using this, one can say,

m<D + m<A = 180

Substitute,

m<ADB + m<BDC + m<A = 180

71 + 42 + m<A = 180

113 + m<A = 180

Inverse operations,

113 + m<A = 180

-113 -113

m<A = 67

There are 160 deer on Manitow Island. The population of deer is growing by approximately 20% per year. Write an equation using d

I believe the equation would be
160+0.2y

Because 160 deer and you round the 20% into a decimal point.
