Answer:

Step-by-step explanation:

The two angles are formed from 2 intersecting lines. The angles are called vertically opposite angles. They are equal

4x + 21 = 85 Subtract 21

4x = 85 - 21 Combine

4x = 64 Divide by 4

x = 64/4

x = 16

Answer:

∠ XZY ≈ 23.6°

Step-by-step explanation:

Using the sine ratio in the right triangle, that is

sinXZY = $\frac{opposite}{hypotenuse}$ = $\frac{XY}{YZ}$ = $\frac{6}{15}$ , then

∠ XZY = $sin^{-1}$ ( $\frac{6}{15}$ ) ≈ 23.6° ( to 1 dec. place )

Answer:

$A_{total} = 25\ ft^2$

Step-by-step explanation:

<u>Step 1: Determine the area of the square</u>

$A = s^2$

$A = (3\ ft)^2$

$A = 9\ ft^2$

<u>Step 2: Split the top figure into a square and triangle</u>

Determine the area of the rectangle

$A = l * w$

$A = (7\ ft - 3\ ft) * (5\ ft - 2\ ft)$

$A = (4\ ft) * (3\ ft)$

$A = 12\ ft^2$

Determine the area of the triangle

$A = \frac{b * h}{2}$

$A = \frac{\frac{7\ ft - 3\ ft}{2} * (5\ ft - 3\ ft)}{2}$

$A=\frac{2\ ft * 2\ ft}{2}$

$A = \frac{4\ ft^2}{2}$

$A = 2\ ft^2$

Since there are two right triangles in the triangle that we have we multiply the area that we got by 2 to get the total area.

$A_{triangle} = 2\ ft^2*2$

$A_{triangle} = 4\ ft^2$

<u>Step 3: Determine the total area</u>

$A_{total} = 9\ ft^2 + 12\ ft^2 + 4\ ft^2$

$A_{total} = 25\ ft^2$

Answer: $A_{total} = 25\ ft^2$

The width of a rectangular garden is 23 and a half feet and the perimeter of the garden is 134 feet. Qhat ia the area of the gar

aleksandrvk [35]

Answer:

1022.25 square feet

Step-by-step explanation:

The length and width sum to half the perimeter, so the length is ...

P/2 -W = length = 134/2 -23.5 = 43.5 . . . . feet

The area is the product of length and width, so is ...

A = LW = (43.5 ft)(23.5 ft) = 1022.25 ft^2

The area of the garden is 1022.25 ft^2.
