Answer 1

Since 3x+17=5x-3, x= 10. so angles

Answer 2

In the parallelogram shown in the image, the opposite angles are the same.

So, ∠D = ∠B (3x + 17 = 5x - 3)

Solve for x.

3x + 17 = 5x - 3

~Subtract 17 to both sides

3x + 17 - 17 = 5x - 3 - 17

~Simplify

3x = 5x - 20

~Subtract 5x to both sides

3x - 5x = 5x - 5x - 20

~Simplify

-2x = -20

~Divide -2 to both sides

-2x/-2 = -20/-2

~Simplify

x = 10

Substitute x with 10 for ∠B

5(10) - 3

50 - 3

47°

Parallelograms have adjacent angles which are supplementary.

So, ∠A + ∠B = 180°

We know that ∠B = 47°, so, solve for ∠A.

∠A + 47 = 180

∠A + 47 - 47 = 180 - 47

∠A = 133°

Therefore, the measure of ∠DAB is 133°

Best of Luck!
