Find the value of y in the right triangle below.

a. 40
b. 90
c. 30
d. 50

A. 50

Step-by-step explanation:

Sum of interior angles of a triangle is always =180 °

Since this is a right triangle, therefore we know that one angle of the triangle measures 90°

Therefor sum of other two angles has to be =

One angle measures = 40°

Therefore the missing angle

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
