When angles complementary, the sum of their mesures is 90 degrees. two complementary angles have measures of 2x-10 degrees and 3x-10 degrees. find the measures of each angle.

34 degrees and 56 degrees

Step-by-step explanation:

As the two given angles are complementary,

2x-10+3x-10=90

5x-20=90

5x=90+20=110

x=110/5=22

x=22

Now each angle

2x-10=2*22-10=34 degrees

and

3x-10=3*22-10= 56 degrees

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

i believe the correct answer is b.
