You would find the are of the triangle (base x height) and subtract it from the area of the circle(pi x diameter)
Answer: Vertical angle proof
Step-by-step explanation: First off, this is really easy if you know how to do it. I think you should be able to figure it out. If you really are in collage. So Vertical angle proof, QPR is essentially (2x-30) but we need to find x. We know a triangle is 180 degrees and if it's a right angle then two angles add to 90.
So x+(2x+30)=90, 3x+30=90, 90-30=60, 3x=60, x=20. So there you have it. Now put x into the equation, 2(20)+30=70
70
C, sorry if its not the correct answer, but I believe it is C
Answer:
3^4 and 81^1
Step-by-step explanation:
3^9 = 19683
3^4 = 81
-9^2 = -81
9^9 = 387420489
81^1 = 81
