Answer:
30
Step-by-step explanation:
90+2x+x=180
3x=90
x=30
First we join the two endpoints of the semicircle and that will be the diameter.
And to find the length of the diameter, we have to use distance formula, with one endpoint (3,2) and the other is (-4,-2) .
SO we get

Radius is half of diameter, so the radius is

Formula of area of circle is

So the area of semicircle is

And the other figure is a triangle, with


Therefore, total area is the sum of area of semicircle and area of triangle,
And we will get

Correct option is the third option .
Then the amount of money will he have in his account after 10 years will be $7,454.16. Then the correct option is B.
<h3>What is compound interest?</h3>

Miguel deposits $5000 in an account earning 4% interest compounded monthly.
Then the amount of money will he have in his account after 10 years will be
We know the compound interest formula.

Where
A = amount
P = principal
r = rate of interest
t = time period (in year)
Then we have

Answer:
C
Step-by-step explanation:
First check if the triangle is right.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side =
and (
)² = 12
2² + (
)² = 4 + 8 = 12
Thus the triangle is right → C
