Answer:
A
Step-by-step explanation:
Change the mixed numbers to improper fractions
7 
= 
6 
= 
The subtraction is then
-
Both fractions have a common denominator so subtract the numerators leaving the denominator
= 
= 
→ A
I'm pretty sure it's 5 over 10! Hope I helped =)
Answer:
Measure of angle R: Measure of angle S:
42 degrees <em><u>90 - 42 = 48</u></em>
30 degrees <em><u>90 - 60 = 30</u></em>
84 degrees <em> </em><em><u>90 - 84 = 6</u></em>
<em><u>Complimentary angles are angles whose sum is 90 degrees</u></em>
Percent change = ((new value) - (old value))/(old value) × 100%
= (180 -135)/135 × 100%
= 33 1/3%
180 is about 33% greater than 135.
<span>The measure of one angle of a triangle is 108. The measures of the other two angles are in a ratio of 1:5
108 + x + 5x = 180</span>
