Answer:

  angle: 44°

  complementary angle: 46°

Step-by-step explanation:

Complementary angles have a sum of 90°. We can use this relation and the one given to write equations for the angles of interest.

__

<h3>setup</h3>

Let 'a' and 'c' represent the angle and its complement, respectively.

  a = c -2 . . . . . an angle is 2° less than its complement

  a +c = 90 . . . . complementary angles total 90°

<h3>solution</h3>

Using the first equation to substitute for 'a' in the second, we have ...

  (c -2) +c = 90

  2c = 92 . . . . . . add 2, collect terms

  c = 46 . . . . . . . divide by 2

  a = 46 -2 = 44 . . . . find 'a' using the first equation

The angle is 44°; its complement is 46°.

Marat540 [252]

Answer:

7/30 of her music library

Step-by-step explanation:

We are looking for 7/10 of 1/3. In this case this "of" means we will multiply the two fractions. To multiply fractions, we multiply

top × top

and

bottom × bottom

1/3 × 7/10

is 1×7 on top, and

3×10 on the bottom.

= (1×7)/(3×10)

= 7/30

7/30 cannot be simplified, so that is the answer.
