You have to recognize the complementary angles are equal to 90 degrees.

Since one angle is 42 degrees. The second angle has to be 48 degrees.

42 + 48 = 90

Q: Two angles are complementary - the second angle measure 42 less the first angle - What is the measure of the 1st angle?

45 degrees

Can't be determined

false but You can find the measure of an exterior angle by using supplementary angles.

60. Complementary angles' measures sume 90

An impossibility because complementary angles add up to 90 degrees but if its a supplementary angle then 180-105 = 75 degrees

If two angles are complementary, then they equal 90 degrees. If one angle is 62 degrees we subtract it from 90 and get 38 degrees.

complementary angles- 2 angles that add up to 90 degrees

Complementary angles add to 90 degrees so the complementary angle to 70 degrees has a measure of 20 deg.

The second angle must be 2 x (90 - 77) ie 26o, so the other is 64o

Lets assume that the first angle is A and the second angle is B. These two angles are complementary so their sum is 90. So if angle A is equal to 35, then this can be plugged into an algebraic formula: A + B = 90 (35) + B = 90 B = 55 The measure of the second angle is 55o

Complementary angles add up to 90*, so a 60* angle's complement is 30*.

Complementary angles total 90o so 90 - 80 = 10; the complementary angle is 10o.

90o

Complementary angles consist of 2 angles that add up to 90 degrees; so the complimentary angle to a 31 degree angle is a 59 degree angle.

the larger angle is 60 and the smaller angle is 30.complimentary angles are 2 angles forming 90 degrees.
