in a triangle, the measure of the first angle is three times the measure of the second angle. The measure of the third angle is

55 more than the measure of the second angle. Use the fact that the sum of the measures of the three angles is 180 to find the measure of each angle to find the measure of each angle.

Let the angles be A, B, C where B is the second angle.

"measure of the first angle is three times the measure of the second angle" =>
A=3B
 
"T<span>he measure of the third angle is 55 more than the measure of the second angle</span>" =>
C=B+55
 
We know that A+B+C=180, =>
A+B+C=180=(3B+B+B+55)
=>
5B=180-55=125
B=25 degrees
A=3*25=75
C=25+55=80
Check: A+B+C=75+25+80=180 ok!

Lubov Fominskaja [6]
Given:
circular merry-go-round that has a diameter of 15 feet.

Find: How much trim does he need to buy to put around the edge of the merry-go-round?

We need to find the circumference of the merry-go-round to get the measurement of the trim needed.

Circumference = π d
π = 3.14
d = diameter = 15 feet

Circumference = 3.14 * 15 feet
Circumference = 47.10 feet.

Mr. Osterhout needs to buy 47.10 feet of trim to put around the circular merry-go-round.

jek_recluse [69]

A pound of oranges cost x dollar => A pound of pears cost x+3 dollar

We have: 8x+4(x+3)=30 => 12x=30-12=18 =>x=1.5

5 pounds of pears cost: 5(x+3)=5(1.5+3)=5*4.5= 22.5 (dollar)
