Answer:

20 =x

Step-by-step explanation:

These angles are vertical angles so they are equal

3x+50 = 6x-10

Subtract 3x from each side

3x-3x+50 = 6x-3x-10

50 = 3x-10

Add 10 to each side

50+10 = 3x-10+10

60 = 3x

Divide by 3

60/3 = 3x/3

20 =x

Answer:

Step-by-step explanation:

Construct a perpendicular bisector of segment AB.

Perpendicular bisector is a line that divides the line into two equal halves forming 90° at the intersection point.

So, points A and B will be at the same distance from the intersection point.

If the constructed line (perpendicular bisector) is the reflection axis, then point B will be the refection point of A.

The length of a rectangle is five times its width.

Marizza181 [45]

ANSWER

96 yd

EXPLANATION

Let the width of the rectangle be w, then, the length of the rectangle will be:

$l = 5w$

The area of a rectangle is calculated using the formula:

$Area=l \times w$

$Area=5w \times w$

$Area=5 {w}^{2}$

It was given that, the area of the rectangle is 320yd²

$320=5 {w}^{2}$

Divide both sides by 5.

$64 = {w}^{2}$

Take square root of both sides to get:

$w = 8yd$

This means the length is

$l = 5 \times 8 = 40yd$

The perimeter of a rectangle is given by:

P=2(w+l)

We plug in the values to get:

$P=2(40 + 8) = 2 \times 48 = 96yd$

The perimeter is 96yd
