Double Points! (i have no clue how to do this)<br> Find the value of the variables in the figure.
Aleks [24]

Answer:

x=12 and y=31

Step-by-step explanation:

First, ( 5x - 7 ) and ( 3x + 17 ) are alternate interior angles, which means they are congruent, or equal:

5x - 7 = 3x + 17

Add 7 to each side:

5x = 3x + 24

Subtract 3x from both sides:

2x = 24

Divide each side by 2:

x = 12

Now we can see that ( 5x - 7 ) and ( 4y + 3 ) are supplementary angles, which means they will add up to 180 degrees:

5x - 7 + 4y + 3 = 180

Substitute 12 in for x to solve for y:

5 ( 12 ) - 7 + 4y + 3 = 180

60 - 7 + 4y + 3 = 180

combine like terms:

( 60 + ( -7 ) + 3 ) + 4y = 180

56 + 4y = 180

Subtract 56 from each side:

4y = 124

Divide each side by 4:

y = 31

2. The perimeter of a rectangle is 72 cm. The width of the rectangle is 16 cm. What is the area of the rectangle?​
tresset_1 [31]
ANSWER
320cm ²

STEP BY STEP
2 widths (16) should equal 32, so you should have 40cm left. Divide 40 by 2 to get one length. Length = 20, width = 16.

So to find the area, you multiply length times width. 20 x 16 = 320

The area is 320cm ²
