Whats The Awnser vertical angles theorem
corresponding angles postulate
same side interior angles theorem
alternate interior angles theorem

angle 1= 81

Step-by-step explanation:

corresponding angles

angle 2 = 180-81 = 99

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:

so, converting firstly the mixed fractions to improper fractions and then "adding".
