Let ∠1, ∠2, ∠3, and ∠4 have the following relationships. ∠1 and ∠2 are right vertical angles. ∠3 is an acute angle adjacent to ∠1. ∠4 is an acute angle adjacent to both ∠3 and ∠2. what is the sum of the measure of ∠1, the measure of ∠2, the measure of ∠3, and the measure of ∠4?

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

step-by-step explanation:

answer: idk

step-by-step explanation:

figure c

step-by-step explanation:

hope this .

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
