Sonja [21]

Answer:

$x=10$

Step-by-step explanation:

we know that

When two lines are crossed by another line (transversal), the angles in matching corners are called Corresponding Angles.

When the line are parallel the corresponding angles are equal in measurement.

In this problem

$(8x+50)\°=130\°$ -----> by corresponding angles

see the attached figure to better understand the problem

Solve for x

Subtract 50 both sides

$8x=130-50$

$8x=80$

Divide by 8 both sides

$x=80/8$

$x=10$

What is area of this

nata0808 [166]

Answer:

A = 20.5 sq units

Step-by-step explanation:

you have the height of 5 but need to figure out the base

we can use the Pythagorean Theorem two times to find it

1) a² + 5² = 7²

a² = 49-25

a = $\sqrt{24}$ = $\sqrt{4}$ · $\sqrt{6}$ = 2 $\sqrt{6}$

2) b² + 5² = 6²

b² = 36-25

b = $\sqrt{11}$

Base = 2 $\sqrt{6}$ + $\sqrt{11}$

A = 1/2 x 5· (2 $\sqrt{6}$ + $\sqrt{11}$ )

A = 2.5 · (2 $\sqrt{6}$ + $\sqrt{11}$ )

A = 2.5(8.2)

A = 20.5
