Hello,
Let's calculate the radius:
r²=5²+7²=74
The circle's equation is (x+5)²+(y+7)²=74
Answer C
(The second one)
Noah ran 8.67 miles in 1 hour and 20 minutes
If we convert the fraction to a decimal (for the miles part) we get 8.67 or 8 2/3 miles.
If 1/3 of an hour is 20 minutes, and an hour is 60 minutes, we add 20 4 times, which gets us to 80, which is 20 past an hour.
Answer:
<h2>58°</h2>
Step-by-step explanation:
We will use the tangent function since we know the opposite and adjacent sides.
Tangent = opposite/adjacent
Tan(e) = 16/10
Tan(e) = 1.6
Use the inverse tangent function to find the angle.
Arctan (1.6) = 57.9946168
Rounding this we get: 58°
<span>A. Find the complement of the angle shown
90 - 52 = 38
</span><span>B. Find the supplement of the angle shown.
180 - 52 = 128
hope that helps</span>
Answer A is the correct equation
