Right trapezoid WXYZ is shown. Right trapezoid W X Y Z is shown. Sides X Y and W Z are parallel. Angle W is 73 degrees and angle
cestrela7 [59]

Answer:

∠WXY = 107°

Step-by-step explanation:

In a trapezoid, adjacent angles are supplementary, meaning they add up to 180°. ∠W and ∠WXY are adjacent, so they are supplementary. 180° - 73° = 107°.

Another way to do this is to know that there are 360° in a trapezoid. This is a right trapezoid, so two of the angles are 90°. One angle is 73°. 90° + 90° + 73° = 253°. 360° - 253° = 107°.

I hope this helps :))

How do i solve -96=-6(1-3b) with the steps
Kay [80]

Answer:

The answer is b= - 5

Step-by-step explanation:

-96 = -6 ( 1 - 3b )

-6 ( 1 - 3b ) = -96

\frac{-6(1 - 3b}{-6} = \frac{-96}{-6}

1 - 3b = 16

3b = 16 - 1 = 15

b= 15 : 3 = 5
