The three angles must add up to 180 degrees.

x - 39 + x - 29 + x = 180       Collect like terms on the left

3x - 68 = 180                        Add 68 to both sides.

3x = 180 + 68

3x = 248  

x = 248 / 3

x = 82.66667

Answer

x = 82,666667 for the largest angle

x - 29 = 53.666667 for the medium size angle

x - 39 = 43.666667 for the smallest size angle

A club raised 175% of its goal for a charity. The club raises $875. What was the goal?
charle [14.2K]

Answer: The goal was $500

======================================================

Work Shown:

x% = x/100

175% = 175/100 = 1.75

Let g be the goal, which is the amount of money the club wanted to raise

175% of goal = 175% of g = 1.75g

The expression 1.75g represents how much money was actually raised, which was $875. Set the two expressions equal to each other. Solve for g

1.75g = 875

g = 875/1.75 ....... divide both sides by 1.75

g = 500

The club's goal was to raise $500

Note how 75% of $500 is 0.75*500 = 375

When they raised 175% of the goal, this means they went 75% overboard and added on 375 additional dollars (on top of the 500 they wanted). So they got to 500+375 = 875 which lines up with the instructions. This helps verify the answer.

Or we can see that 1.75*g = 1.75*500 = 875 which helps confirm the answer as well.
