Answer:
The cost of the old ball was $100.
Step-by-step explanation:
The cost of the new ball = $300
The new ball has three times the price of his old ball.
So, let the price of the old ball be = x
As per situation, we get the equation:

Dividing both sides by 3:

=> x = 100
Hence, the cost of the old ball was $100.
Using the interactive protractor, the measure of the angle JHG is 115°
<h3>How to determine the measure of the angle?</h3>
The image that completes the question is added as an attachment.
The question requests that we determine the measure of JHG using a protractor.
To do this, we set one end of the protractor at 0°.
Then, we take the measurement of the other end
Using the interactive protractor, the other end stops at 115°
Hence, the measure of the angle JHG is 115°

Answer:
Triangle 1: x = 80 degrees, acute
Triangle 2: x = 10 degrees, right
Step-by-step explanation:
Triangle 1:
By the Sum of Interior Angles Theorem, all the angles inside the triangle adds up to 180 degrees. So, set up this equation:

Solve for x:

So, x = 80 degrees
Because all the angles are less than 90 degrees, this is an acute triangle.
Triangle 2:
By the Sum of Interior Angles Theorem, all the angles inside the triangle adds up to 180 degrees. So, set up this equation (with the right angle given):

Solve for x:

So, x = 10 degrees
Because there is an angle measuring 90 degrees, this is a right triangle.
900. You round up, because it is above 850. :-)
