$\angle D =\angle B\\\\
\angle B=\angle A+30\\
\angle A+ \angle B=180\\\\
\angle A+\angle A+30=180\\
2\angle A=150\\
\angle A=75\\\\
\angle B=75+30=105\\
\boxed{\angle D=105}

Find the area of the composite figure in terms of the figure (use 3.14 for pi)

svp [43]

Answer:

105.12 ft²

Step-by-step explanation:

Let's first find the area of the rectangle.

$10\cdot8=80$ ft², so the rectangle has an area of 80ft².

To find the area of the semi-circle, we find the area of a whole circle and divide by two.

The formula to find the area of a circle is $\pi r^2$ . The radius is 4, as the diameter is 8.

$3.14\cdot4^2$

$3.14\cdot16$

$50.24\div2=25.12$

Add 80 and 25.12:

$80+25.12=105.12$

Hope this helped!

Pair 2 is a reflection. If you rotated it it would be flipped, so that doesn’t make sense.

Can anybody write an equation for the following word story:

Rudiy27

40=6.95c+5.25
The $40 is what you want it all to equal, so that goes to one side by itself.
The CDs are 6.95 each, so they get a variable to show that.
The 5.95 is added to that, showing that it's only charged once.
Then, all you have to do is solve for c, which is the number of CD's you can buy.
