Answer:

Step-by-step explanation:
Since we are given the hypotenuse which is 18 since it slanted, and leans on the house. And we are given one of the legs which is 15 since it is vertical. We can use the pythagorean theorem to solve for this problem.

where a and b are the legs and c is the hypotenuse l.
Let plug it in






Answer:
1
Step-by-step explanation:
x is 1 and y is 1 and the total is three so 1
Answer:
128
Step-by-step explanation:
86 plus 87 plus 91 =264
You have to get 98 times 4 which is 392
Then;
392-264, which is 128, which is the answer (the fourth number)
So;
86+87+91+128 = 392 divided by 4 (the number of numbers there is) which equals 98!

Using supplementary angles, it is found that the measure of angle x is of 65º.
<h3>What are supplementary angles?</h3>
Angles are called supplementary if the sum of their measures is of 180º.
In this problem, angles x, 25, and 90º are supplementary, hence:
x + 25 + 90 = 180
x = 180 - (25 + 90)
x = 65º.
The measure of angle x is of 65º.
