Step-by-step explanation:

Remark

The angles are marked as alternate interior angles. To be parallel, they must be equal. In other words x - 20 must equal 52. That's all you have to do. Just equate the 2 givens and solve.

Givens

x - 20 is one angle

52 is the other.

Solution

x - 20 = 52 Add 20 to both sides.

x - 20 + 20 = 52 +20 Combine

x = 72

3 2 ? start fraction, 2, divided by, 3, end fraction of the doughnuts in a box have frosting. \dfrac12 2 1 ? start fraction, 1,

timurjin [86]

Answer:

$\frac{1}{3}$ of the doughnuts in the box have frosting and sprinkles.

Step-by-step explanation:

If there are $x$ doughnuts in the box. Then, $\frac{2}{3} \times x = \frac{2x}{3}$ of the doughnuts in the box have frosting. Therefore, $\frac{1}{2} \times \frac{2x}{3} = \frac{1}{3}x$ of the doughnuts with frosting have sprinkles. This implies that $\frac{1}{3}$ of the doughnuts in the box have frosting and sprinkles.
