Solution

A +B+C=180(Sum of angles of triangle )

A+90+52=180

A=180-(90+52)

A=38

Now,

Taking A as perpendicular

AC = Hypotenuse

BC=Perpendicular

BA= Base

Below

Step-by-step explanation:

1)  the measure of angle A is 38, because all angles of a triangle must add up to 180 degrees so:

                                                    52+90+A=180

                                                       142+A=180

                                                          A=38

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

the answer would be 0.54
