Angle A and C are.

1- congruent
2- supplementary

2- Supplementary

Step-by-step explanation:

Since both Angles A and C lie on the same line, they are supplementary. Supplementary angles add up to 180°.

Congruent angles are equal. Here, if Angles A and C are congruent, they would be 180° ÷ 2 = 90° each, so congruent is the wrong answer.

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

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 im pretty sure that is the right answer
