Answer:
a) Angle XBC = 55° because it's a corresponding angle
AXY = XBC
b) 180° - (55° × 2) = 70°
happy with solution rate this
To find the diameter, divide the area(254.34) by pi(3.1415) and then square the quotient


That is the radius now just times that by 2 so 2 x 8.99 = 17.98
Now I have a felling the might be wanting 18 because 8.99 is so close to 9 and this is also true for 80.95. They probably want 80.95 = 81, which the square root of that is 9, which is the radius and if you times that by 2 the diameter would equal 18
Multiply the two as area is base times height.
Answer:
a) 42.8 degrees.
Step-by-step explanation:
sin-|(-0.27 +0.95) means the angle whose sine is (-0.27+0.95)
= sin-1(0.68)
Using a calculator the answer is 42.8 degrees.
