What is the measure of the angle labeled (5x+42)° ?

barxatty [35]

We see two parallel lines crossed by a transversal.

The two labelled angles are alternate interior angles, hence they are equal.

The equality allows us to equate the two expressions and hence solve for x.

8x-3=5x+42

transpose terms

8x-5x=42+3

solve for x

3x=45

so x=45/3=15.

This means 5x+42=5*15+42=75+42=117 degrees.

Find the area of the composite shape

Alexxandr [17]

Answer:

$13.735$ $ft^{2}$

Step-by-step explanation:

Area of a circle.

$A=\pi r^{2}$

$r=d/2\\r=8/2\\r=4$

$A=\pi \times 4^{2}$

$A=16\pi$

$A \approx 50.2654824574$

Area of a square.

$A=s^{2}$

$A=8^{2}$

$A=64$

Subtract the area of the square with the area of the circle.

$64-50.2654824574$

$= 13.7345175426$

I hope it helps.

Brainliest much appreciated.
