Answer:

x=5 y=38

Step-by-step explanation:

180 degrees total minus the right angle (90) = 90... divide that by the two angels and its 45 each so for x; 45/3 = 5 for y; 45-7= 38

Answer:

y=−3x+83

x= −1 /3 y+ 83 /3

Step-by-step explanation:

right angles=90

triangles=180 degrees

180=3x+y+7+90

solve for x

3x+y+97=180

Add -y to both sides

3x+y+97+−y=180+−y

3x+97=−y+180

Add -97 to both sides

3x+97+−97=−y+180+−97

3x=−y+83

Divide by 3

x= −1 /3 y+ 83 /3

now solve for y

180=3x+y+7+90

Add -3x to both sides

3x+y+97+−3x=180+−3x

y+97=−3x+180

Add -97 to both sides

y+97+−97=−3x+180+−97

y=−3x+83

The square has a side length of 10 ft and the circle inside the square has a diameter of 10 ft find the approximate area of the

Sphinxa [80]

Answer:

$Area = 21.5ft^2$

Step-by-step explanation:

See attachment

Given

Square:

$Length = 10ft$

Circle:

$Diameter = 10ft$

$\pi = 3.14$

Required: Calculate the area of the shaded region

First, calculate the area of the square:

$A_1 = Length^2$

$A_1 = (10ft)^2$

$A_1 = 100ft^2$

Next, the area of the circle.

$A_2 =\pi * \frac{d^2}{4}$

$A_2 =3.14 * \frac{10^2}{4}$

$A_2 =3.14 * \frac{100}{4}$

$A_2 =3.14 * 25$

$A_2 =78.5ft^2$

The shaded region has the following area

$Area = A_1 - A_2$

i.e. the difference between the area of the square and the area of the circle

$Area = 100ft^2 - 78.5ft^2$

$Area = 21.5ft^2$
