Question

What is the length of JL, nearest tenth

Answer 1

Answer:

I believe the answer is 45.

Step-by-step explanation:

a 90 degree angle is represented by a square on the corner.

So half of 90 is:

90 ÷ 2 = 45

the angle next to the letter M is 90 degreess, so the other side of the line is also 90 degrees.

45 + 90 = 135

and 180 - 135 = 45

(You subtract 135 from 180 since " the sum of angles of a triangle equals the straight angle", which is 180 degrees.

So, the length of JL is equal to 45 degrees.
