y = x + 5


If it's perpendicular the slope is the opposite inverse of the other line,


The slope of line y = x + 5 is 1, because it's the number before x, so, the opposite inverse would be -1/1 = -1.

Find the measure of angle A. This is for my math class, and I’ve been stuck on this for a while. Please help!
Kruka [31]

Answer:

20°

Step-by-step explanation:

The sum of angles in a ∆ = 180°

Therefore, (17x - 1) + (3x - 4) + 25 = 180

Use this expression to find the value of x, then find the measure of angle A.

17x - 1 + 3x - 4 + 25 = 180

17x + 3x - 1 - 4 + 25 = 180

20x + 20 = 180

Subtract 20 from both sides

20x + 20 - 20 = 180 - 20

20x = 160

Divide both sides by 20

\frac{20x} = \frac{160}{20}

x = 8

Find measure of angle A.

Angle A is given as 3x - 4

Plug in the value of x and solve

A = 3(8) - 4 = 24 - 4 = 20

Answer:

x=6

Step-by-step explanation:

Hi there!

<u>1) Determine the perimeter of the square</u>

We're given that the perimeters of the square and the rectangle are equal. Therefore, after finding the perimeter of the square, we will also know the perimeter of the rectangle.

Find the side length of the square using the area formula:

A=l^2 where l is the side length

Plug in the given area 121 in.²

121=l^2

Take the square root of both sides

\sqrt{121} = \sqrt{l^2} \\11=l

Therefore, the side length of the square is 11 inches. Plug this into the perimeter formula:

P=4l where l is the side length

P=4(11)\\P=44

Therefore, the perimeter of the square is 44 inches. The perimeter of the rectangle is also 44 inches.

<u>2) Determine the value of x</u>

Use the formula for the perimeter of a rectangle:

P=2(l+w) where l is the length and w is the width

Plug in 3x and x-2 as the length and width

P=2(3x+(x-2))\\P=2(3x+x-2)\\P=2(4x-2)

Plug in the perimeter 44 in.

44=2(4x-2)

Expand the parentheses

44=8x-4

Add 4 to both sides to isolate 8x

44+4=8x-4+4\\48=8x

Divide both sides by 8 to isolate x

\frac{48}{8}=\frac{8x}{8}  \\6=x

Therefore, the value of x is 6.

I hope this helps!
