Answer:
24.99
Step-by-step explanation:
If the area of the quarter circle is 38.465, then the equation to find this would be
3.14*r^2 / 4 = 38.465. we solve for r, the radius, and get two solutions. 7 and -7. Obviously the length of the radius can't be -7, so we know the radius is 7.
Now we must solve for the perimeter. The perimeter is equal to 2r + (2*3.14*r)/4
Plugging 7 in as the radius, r, we get 24.99 as our final answer.
x+x+96=180
2x=180-96
2x = 84
divide both sides by 2
x=42degrees
Then the other angle = 180-42
=>138°
Proof: If I add 96 to the first angle, I will get the second angle.
=> 42+96= 138°
Divide and do a notebook
Check from calculator
And afterwards consult if any problems
