Question

What is m∠L?



Enter your answer in the box.

°

Answer 1

We are given a triangle JKL.

<J =5x°

<K = 2x°

<L = 3x°.

Note: Sum of angles of a triangle is 180°.

Therefore, <J +<K+<L = 180°.

5x +2x+3x = 180°.

10x = 180

Dividing both sides by 10, we get

10x/10=180/10

x = 18.

We need to find the m<L.

m<L =3x° = 3(18) = 54°.

Therefore, m<L = 54°.
