Answer:
x = 17.
Step-by-step explanation:
We know that the two angles are supplementary (equal 180) as they are found on a straight line. Therefore,
(5x - 18) + (4x + 45) = 180.
9x + 27 = 180.
9x = 153.
x = 17.
Answer:
380.13
Step-by-step explanation:
Use the formula A = π r squared
A= π (11)squared
To solve this you will you the Pythagorean Theorem.
the equation for the Pythagorean Theorem is a²+b²=c².
fill in the information you have:
a²+3²=5²
now solve for a:
a²+9=25
-9 -9
a²=16
√a²=√16
a=4
The length of the side a of the right triangle is 4.
