The measures of two complementary angles are 64 degrees and 26 degrees

<h3><u>Solution:</u></h3>

Let the larger angle be "a" and smaller angle be "b"

<em>Two angles are Complementary when they add up to 90 degrees</em>

so we get,

a + b = 90 ------ eqn 1

Given that measure of the larger angle is 12 more than twice the measure of the smaller angle

larger angle = 12 + 2(smaller angle)

a = 12 + 2b --- eqn 2

<em><u>Let us solve eqn 1 and eqn 2 to get values of "a" and "b"</u></em>

Substitute eqn 2 in eqn 1

12 + 2b + b = 90

12 + 3b = 90

3b = 90 - 12

3b = 78

<h3>b = 26</h3>

Therefore from eqn 2,

a = 12 + 2b

a = 12 + 2(26)

a = 12 + 52

<h3>a = 64</h3>

Thus the measures of two complementary angles are 64 degrees and 26 degrees

How to simplify an expression with a negative exponent
svetlana [45]

Answer:

Step-by-step explanation:

An negative exponent seems hard, but it really isn't!

Let's say you have 2^{-3}

All you do is inverse the expression, or find the reciprocal. When you do this the exponent changes to positive .  

\frac{1}{2^{3} }

2^{3} simplifies into 8. So, the result is

\frac{1}{8}

Hope this helps! Please mark as brainliest, thanks!

Kate made 4 dresses with 7 yards of fabric. how many yards did she use on 1 dress
Ksju [112]
This is a fraction equal to
7 yards ÷ 4 dresses

We want a unit rate where
<span>1 is in the denominator, </span>
so we divide top and bottom by 4.

7÷4= 1.75
_
4÷4=1.
Therefore, Kate used 1.75 yards per one dress (1.75 yds. p/ d)

Hope I helped! :)
