Its a geometry question i do not understand.

Check out the attached image. Since the two angles PQS and SQR are adjacent and form angle PQR, this means we simply add up the angles

(Angle PQR) = (Angle PQS) + (Angle SQR)

Angle PQR = 87 + 33

Angle PQR = 120 degrees

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

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
