Answer:

it's and isoceles triangle so the base angles will be the same.

28 + 28 + 9 = 65

180-65=115

5x = 115

115/5 =23

23 X 5 + 9 = 124 degrees

Answer:

x=23

Step-by-step explanation:

The first triangle has two sides that are the same, therefore the two bottom angles are the same as well, so the two bottom angles equal to 56 degrees of the total 180 degrees that a triangle should have. That leaves the last angle to be 124 degrees.

Now what you do is subtract 9 from 124 to get 115

Lastly divide 115 by 5 to get 23.

Paul needs to buy paint to cover all outside surfaces of his shed, depicted below. How much area, in square yards, does he need
Alekssandra [29.7K]

Answer:

Area = 145.7 Square yards

Step-by-step explanation:

Since there is no picture attached to depict the house and its dimension, I am taking values of a similar problem.

<em><u>Dimensions of Shed</u></em>

2 walls with dimensions of 15 ½ ft. by 12 ft.

2 walls with dimensions of 25 ¼ ft. by 12 ft.

Ceiling with dimensions of 15 ½ ft. by 25 ¼ ft.

2 windows that are each 2 ft. by 4½ ft. as well as an 8-ft. by 5-ft. door

<u>Solution</u>

We need to find the total wall area and ceiling area which when combined will give us the total area shed's outer surface that needs to be painted.

For total area of the wall, we need to first find the sum of area for each wall and subtract area of windows and door

Wall Area = Area of 1st two walls+Area of other two walls-Area of 2 windows-Area of door=[15.5(12)(2)] + (25.25) (12) (2) - (2)(2) (4.5) -(8)(5)

Wall Area = 371 + 606 - 17 - 40

Wall Area = 920 square ft = 102.2 square yards

Ceiling Area is just the area of the ceiling

Ceiling Area = (15.5) (25.25 )

Ceiling Area = 391.375 square ft= 43.486 square yard

<u>Total Area = Wall Area+Ceiling Area </u>=102.2+43.486=145.7 Square yards

Which is the area paul needs to cover with paint.

<em>Note: Converted Square foot to square yard as the problem requires that.</em>

A cube has a surface area of 384 square inches. What is the edge lenth of the cube? Explain pls
m_a_m_a [10]
Since there are 6 sides to a cube we can divide the total surface area by 6 to find the area of a single side

384 / 6 = 64

since the side of a cube is a square the sides are the same length, so we need a number, that when multiplied by itself is 64. The answer is 8
