Answer:x=65 y=40
Step-by-step explanation:
1) solve for x in the second triangle by adding each degree together and setting it equal to 180 (every triangle equals 180°)
2) x should equal 65
3) do the same for the first triangle except plug in 65 (since we know it equals x) and solve for y.
For a question like this, order of operations must be followed. This can be expressed with PEMDAS.

8^2 ÷ 4 + 3.7(42.3-24.6) -------> Parenthesis first
8^2 ÷ 4 + 3.7(17.7) ------> Now exponents
64 ÷ 4 + 3.7(17.7) ------> Now multiplication and division
16 + 65.49 --------> And finally addition
81.49 which is answer choice C

The answer is x = 6
Let us first define x to be the number of hours of riding lessons she can take.
X = Hours of lessons
Now, she has $200, she needs to pay $20 for grooming supplies, and the lessons cost $30 an hour. We to find the maximum amount of hours of lessons she can take, so in other words, we want to make her broke. To do this, we first convert the words into an equation:
200 - 20 - 30x = 0
Simplifying, we get
180 = 30x
x=6
