We know that m<JKL = m<JKM + m<MKL

Let's substitute the values from the picture into our equation above.

10x - 11 = 43 + 8x - 20

Combine like terms.

10x - 11 = 8x + 23

Subtract 8x from both sides and add 11 to both sides.

2x = 34

Divide both sides by 2

x = 17

m<MKL = 8x - 20 = 8(17) - 20 = 136 - 20 = 116 degrees.

m<JKL = 10x - 11 = 10(17) - 11 = 170 - 11 = 159 degrees.

The radius of a circle is 10 meters. What is the angle measure of an arc 3 meters long?

Anuta_ua [19.1K]

Answer:

Ф = 0.3 radians

Step-by-step explanation:

The arc length formula is s = rФ. Solving for the angle measure Ф, we get:

Ф = s/r

and so with r = 10 m and s = 3 m, we get Ф = 3 m / 10 m = Ф = 0.3 radians
