|
Answer» y = 144 degreex = 54 degreeStep-by-step explanation:FOR angle yangle AOB = 180 angle ( AOD + DOB ) = 180 36 + angle y = 180 angle y = 180 - 36 angle y = 144FOR angle xangle ACB = 90 ( angle in semicircle is 90 )angle CAB = 36angle ABC = xsum of angles of triangle = 180IN TRIANGLE ABCangle CAB + angle ABC + angle ACB = 180 90 + 36 + x = 180 x + 126 = 180 x = 180 - 126 x = 54 |
