2x=76 since oposite angles are equal
2x=76
divide 2
x=38

on line, angles add to 180
2x+y=180
76+y=180
minus 76 both sides
y=104

y=104
x=38

3rd option

2nd option bc x and y are supplementary, therefore they equal 180. 52 x 2 = 104. 104 +76 = 180. and it can also be the third option because they equal 180.

Martin uses 5/8 of a gallon of paint to cover 4/5 of wall. What is the unit rate at which Martin paints in walls per gallon
MAVERICK [17]

Answer:

24/25 walls per gallon

Step-by-step explanation:

to get per gallon, we want gallon to be zero.

5/8 gallon of paint: 3/5 of wall

multiply by 8/5 on both sides

1 gallon: 24/25 of wall

24/25 walls per gallon.

Find the perimeter of a rectangle whose length is 3 cm greater than its height, and whose area is 40 cm².
jonny [76]

Answer: 26\ cm

Step-by-step explanation:

The perimeter of a rectangle can be calcualated with this formula:

P=2l+2h

Where "l" is the lenght and "h" is the height.

 The area of a rectangle can be found with this formula:

A=lh

Where "l" is the lenght and "h" is the height.

In this case we know that:

A=40\ cm^2

Therfore, we can susbsitute them into A=lh and solve for "h" in  order to find its value:

40=(h+3)h\\\\40=h^2+3h\\\\h^2+3h-40=0

Find two number whose sum is 3 and whose product is -40. These are -5 and 8. Then, factorizing, we get:

(h-5)(h+8)=0\\\\h_1=5\\\\h_2=-8

The positive value is the height. Then:

h=5\ cm

Since the length is 3 centimeters greater than its height, we get that this is: Then:

l=5\ cm+3\ cm\\\\l=8\ cm

Substituting values into P=2l+2h, we get that the perimeter is:

P=2(8\ cm)+2(5\ cm)\\\\P=26\ cm
