Answer:

These are corresponding angles, which means that there angle measurements would equal the same. Corresponding angles have the same relative position at intersections (as shown by x and 110).

1) Angle Pair: Corresponding Angles

2) By using the definition of Corresponding Angles, we can derive that x = 110.

Use 3.14 for PI( π ) Diameter: 5 ft Formula: A= πr2

Liula [17]

Answer:

$\boxed {\boxed {\sf 19.625 \ ft^2}}$

Step-by-step explanation:

The area of a circle is found using this formula:

$a= \pi r^2$

We know the circle's diameter is 5 feet, but we don't know the radius. Remember the diameter passes through the center from one side to the other, while the radius connects the center and the side. Therefore, the radius is half the diameter.

r=d/2
r= 5 ft/2
r= 2.5 ft

We know the radius is 2.5 feet and we are using 3.14 for pi. Substitute the values into the formula.

$a= (3.14)* (2.5 \ ft)^2$

Solve the exponent.

(2.5 ft)²= 2.5 ft *2.5 ft=6.25 ft²

$a= (3.14)*(6.25 \ ft^2)$

Multiply.

$a=19.625 \ ft^2$

The area of the circle is 19.625 square feet.

Using trig to solve for missing angles

Sveta_85 [38]

Answer:

? = 32.20422

Step-by-step explanation:

We know the adjacent side and the hypotenuse

cos ? = adj / hyp

cos ? = 33/39

cos ? = 11/13

Taking the inverse cos of each side

cos ^ -1( cos ?) = cos^-1(11/13)

? = 32.20422

The width of a rectangular pool is 5 meters longer than the length. The perimeter of the pool is 58 meters. Use and equation to

garri49 [273]

The perimeter of a rectangular pool = 2l + 2w

If the width is 5m longer than the length,

Then Perimeter = 2(l + 5) + 2l
= 4l + 10 {THE EQUATION}

Since Perimeter = 58 m
Then 4l + 10 = 58 m

⇒ l = 12 m

Thus the Length of the Pool = 12 m
