Answer:

see explanation

Step-by-step explanation:

(a)

The angle on the circumference is half the central angle , that is

∠ A = ∠ BOC ÷ 2 = 50° ÷ 2 = 25°

(b)

Δ AOC is isosceles ( OA = OC , radii of the same circle ) then the base angles are congruent , that is

∠ ACO = ∠ A = 25°

(c)

Δ BOC is isosceles ( OB = OC, radii of the same circle ) then the base angles are congruent, that is

∠ BCO = $\frac{180-50}{2}$ = $\frac{130}{2}$ = 65°

(d)

∠ ACO + ∠ BCO = 25° + 65° = 90° ( angle in a semicircle )

10. If R is the midpoint of QS, find QS.

Art [367]

Statement:

R is the midpoint of QS.

To find out:

The measure of QS.

Solution:

QR + RS = QS
Since R is the midpoint of QS, then QR = RS.
QR = 2x + 16, RS = 5x - 17.
Therefore, 2x + 16 = 5x - 17
or, 2x - 5x = -17 - 16
or, -3x = -33
or, x = -33 ÷ -3
or, x = 11
Therefore, QR = 2(11) + 16
= 22 + 16 = 38
So, QS = 2QR
= 2 × 38
= 76

Answer:

QS is 76.

Hope you could understand.
