A) What is the value of mL1 to be if

<1 and <2 are complementary angles and m L2 = 85° ?

1 answer

If <1 and <2 are complementary angles, that means their sum is 90 degrees. Let mL1 represent the measure of angle <1.

We know that mL2 = 85°, so the measure of <1 is:

mL1 + 85° = 90°

Subtracting 85° from both sides of the equation, we get:

mL1 = 90° - 85°

mL1 = 5°

Therefore, the value of mL1 is 5 degrees.
