isosceles triangles means that the two bottom angles and sides are equal

therefore, you can set R and T equal to each other:

(15x-31)=(9x+11)

(get x to one side)

15x=9x+42

6x=42

x=7

now you can plug x back into the equations:

15(7)-31

105-31

74

R and T = 74

all triangles' internal angles = 180

therefore you can add the two angles then subtract them from 180

74+74=148

180-148=32

S should be 32 :)

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
