10. 79 and x are vertical angles so they are equal to each other
11. 62 and x are complentary so they should add up to 90. Subtract 62 from 90 or setup the equation 62+x=90 to find your answer
12. 47 and x are supplementary angles so they add up to 180. Subtract 47 from 180 or setup the equation 47+x=180 to find your answer
13. 43+x must equal 90 because the two angles are complementary. After solving for that, subtract 90 from 180 to find y.
14. To find x subtract 88 from 180. x and z are vertical angles so they are equal, and 88 and y are vertical angles so they are also equal.
15. To find x subtract 90 from 180. To find y add 42 and 53 and subtract it from 180.

Solve for j.<br> J + 22/8 =8

Monica [59]

Answer:

j=5.25

Step-by-step explanation:

j+22/8=8

j=8/1-22/8

j=64-22/8

j=5.25

Proof:

5.25+22/8=8

525/100+22/8=8

4200+2200/800=8

6400/800=8

8=8

Demarcus has to wrap a gift for his friend's birthday party. the gift is in a rectangular box with the dimensions shown below. h

Leya [2.2K]

The gift wrap needed by Damarcus = total surface area of a rectangular box = 1,048 in.².

<h3>What is the Total Surface Area of a Rectangular Box?</h3>

Total surface area (TSA) = 2(wl+hl+hw), where:

l = length
w = width
h = height of the box.

The amount of gift wrap needed to cover the whole box = total surface area of the rectangular box

l = 20 in.

w = 8 in.

h = 13 in.

Plug in the values into the formula for total surface area of a rectangular box:

TSA = 2(8×20 + 13×20 + 13×8)

TSA = 1,048 in.²

Therefore, the gift wrap needed by Damarcus = total surface area of a rectangular box = 1,048 in.².

yulyashka [42]

Answer:

$m=4$ or $m=\frac{4}{1}$

Step-by-step explanation:

To find slope we use the slope formula

$m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

Two points on the line we can classify are (3,4) and (4,8)
