Find the value of the indicated angles.

Part 1) The measure of the angle is 47°

Part 2) The measure of the angle is 52°

Step-by-step explanation:

Part 1)

we know that

The inscribed angle is half that of the arc it comprises.

we have that

(12y-1)°=(9y+11)° > because the arc that the inscribed angles comprise is the same

Solve for y

12y-9y=11+1

3y=12

y=4°

Find the measure of the angle

(12y-1)°=12(4)-1=47°

Part 2)

we know that

The inscribed angle is half that of the arc it comprises.

we have that

2(3m+2)°=(4m+20)° > because the arc that the inscribed angles comprise is the same

Solve for m

6m+4=4m+20

6m-4m=20-4

2m=16

m=8

Find the measure of the angle

(4m+20)°=4(8)+20=52°

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
