3. The sum of the measures of a complement and a supplement of an angle is 200. What is the measure of the angle?

klasskru [66]

Hi there!

Let th' required angle = X

Then,

• Complement of th' angle = 90 - X
• Supplement of th' angle is = 180 - X

According to th' question,
Sum of Complement and Supplement :-

(90 - X) + (180 - X) = 200

⇒ 90 - X + 180 - X = 200

⇒ 270 - 2X = 200

⇒ 2X = 270 - 200

⇒ 2X = 70

⇒ X = $\dfrac {70}{2}$ = 35

Hence,
Th' measure of the angle is 35°

~ Hope it helps!

Alex777 [14]

Answer:

1. Yes

2. Yes

Step-by-step explanation:

Leah wrote 2 different fractions with the same denominator. Both fractions were less than 1.

1. Can their sum equal 1?

Let Leah fractions be $\dfrac{6}{7}$ and $\dfrac{1}{7}.$ Both these fractions have the same denominators and are less than 1. Find their sum:

$\dfrac{6}{7}+\dfrac{1}{7}=\dfrac{7}{7}=1$

2. Can their sum be greater than 1?

Let Leah fractions be $\dfrac{6}{7}$ and $\dfrac{5}{7}$ . Both these fractions have the same denominators and are less than 1. Find their sum:

$\dfrac{6}{7}+\dfrac{5}{7}=\dfrac{11}{7}=1\dfrac{4}{7}>1$

Kevin runs 8 miles in 84 minutes. At the same rate, how many minutes would he take to run 6 miles?

netineya [11]

Kevin runs:

8 miles -- 84 minutes;

6 miles -- x minutes.

Write a proportion:

$\dfrac{8}{6}=\dfrac{84}{x}.$

Then $8\cdox =6\cdot 84,\\ \\x=\dfrac{6\cdot 84}{8}=3\cdot 21=63\ minutes.$

Answer: it takes him 63 minutes to run 6 miles
