Answer:
Step-by-step explanation:
A quarter circle is one fourth of a circle. To find the area of a quarter circle, find the area of the whole circle by using the formula A = pi * r^2 and then divide by 4. To find the perimeter of the quarter circle, find the circumference of the whole circle, divide by 4, and then add the radius twice.
ET is tangent to circle A so ET is perpendicular to AT
So <ATE = 90°
Given <TNG = 35°
<NET = <ATE - <TNG
= 90° - 35°
= 55°
Answer is 55°
Okay first off. You want to combine like terms.
2.75-1.5=1.25j
2.25+3=5.25
Now you just fit those two answers into the final answer and you have:
1.25j+5.25.
