Answer: C. 17.5 feet
Step-by-step explanation:
The attached photo shows the triangle ABC formed by the ladder and the wall. It is a right angle triangle because one of its angles is 90 degrees. The ladder is the hypotenuse of the triangle. To determine the height of the wall, we would find BC by applying Pythagoras theorem
Hypotenuse^2 = opposite ^2 + adjacent^2
18^2 + 4.5^2 + BC^2
BC^2 = 324 - 20.25 = 303.75
BC = √303.75 = 17.5 feet.
now, let's notice the minor arc of 26x°, let's recall that a circle has a total of 360°, thus if the minor arc is 26x°, then the major arc has to be the difference of 360 and that much, namely 360 - 26x.

Answer:
9.5
Step-by-step explanation:
Since he did 38 miles in 4 hours, we need to divide it by 4 to find mph. 38/4 = 9.5
therefore, his speed his 9.5 mph
I hope this helped, and if my answer was right, please mark this answer as brainliest! Thank you!
Answer:
False
Step-by-step explanation:
B is the y-intercept.
Your answer is 1:-4. This is because when you divide each term by -4, that is the number in the next term.
