Find the value of a.
In right triangle LMN, angles L and M are complementary.
Find the mesure of angle L.

Answer 1

Answer:
Question 1:
So it’s a straight angle which means it’s equal to 180 degrees. There’s also a right angle, so we can subtract that, now what’s left is 90 degrees. That means,

51 + a = 90

Solve:

a = 39

Second:

Complementary means it’s equal to 90 degrees, therefore we can make an equation of

L + 51 = 90

Solve

L = 39

So for both questions, the answer is 39 degrees
