Answer:
C
Step-by-step explanation:
It's the only acute angle.
For this case we have that by definition of properties logarithm is met:

So, rewriting the expression we have:

By definition of logarithm we have to:
is equivalent to
So:

ANswer:

Answer: B. x = 40
Step-by-step explanation:
The angles given are supplementary.
Supplementary angles are any two angles that add to 180 degrees, most commonly seen on one side of a straight line.
As these angles are supplementary, we can solve for x by adding both angles to get 180:

This means that the angle on the left is (3*40) + 15, or 135 degrees, while the angle on the right is 45 degrees. These angles add to 180 degrees.
The correct answer choice is B.
Answer:
I’m stuck
Step-by-step explanation:
Answer:
X = 25.28
Step-by-step explanation:
By Pitagoras Theorem:
9^2 + Y^2 =24^2
81 + Y^2 = 576
Y^2 = 495
Y = 22.25
Now Y is one catet for to find X
X^2 = 12^2 + 22.5^2
X^2 = 144 + 495
X^2 = 639
X = 25.28
