Answer:

Step-by-step explanation:
We are given the function:

and asked to find f(5). Therefore, we must substitute 5 in for each
.

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Multiply 18 and 5.

Add 90 and 11.

f(5) is equal to 101.
Answer:
Step-by-step explanation:
in the first triangle an angle is 60 degrees so it means that the triangle is half of a equilateral triangle.
in this case the base leg is half of the hypotenuse.
x = 8
in the second triangle we have an angle that is 45 degrees and this means that the triangle has two congruent legs
x = 10
