Measurement of 1 and 2 are complementary.

1=x°

2 = 3x+30°

15

Step-by-step explanation:

If two angles are complementary, they add up to 90 degrees.

So ∠1 + ∠2 = 90.

Which means that:

x + 3x + 30 = 90

Continue to simplify.

4x + 30 = 90

4x = 60

x = 15

The measure of angle 1 is 15.

90 - 15 = 75

The measure of angle 2 is 75.
