Question

Ray QK is the angle bisector of ÐLQM. If mÐ6 = 4x + 12 and mÐ7 = 7x – 9, find the degree measure of ÐLQM.
Select one:
a. 49°
b. 40°
c. 20°
d. 80°

Answer 1

Now, the sum of an angle of a straight line is 180 degrees. Now, since they gave you 2 parts, you would add them and set them equal to 180 so

Answer 2

11x+3=180

Answer 3

I will solve for you, cause I typed wrongly.

Answer 4

Ok, a angle bisector cuts an angle in half. Since they cut 6 and 7 in half, you would set them equal to each other.

Answer 5

So, it would be 4x+12=7x-9

Answer 6

after you solve for x which is 7, you would plug it back in so.

Answer 7

4(7)+12+7(7)-9=28+12+49-9=80, so the answer is 80 degrees.

Answer 8

thanks (:
