What is the approximate measure, in degrees, of the central angle of the circle whose radius is 15 m and arc length is 10 m?

Step-by-step explanation:

we know that

The circumference of a circle is equal to

we have

substitute

Remember that

degrees subtends the complete circle of length  

so

by proportion

Find the approximate measure, in degrees, of the central angle of the circle whose radius is 15 m and arc length is 10 m

so

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

the first one, all those points on the line just make a strait line.
