Consider the given functions,
Solve for f(2) as,
Thus, the value of f(2) is equal to 1 .
Solve for inverse of f(1) as,
Thus, the value of f(2) is equal to 1 .
Answer:
A
Step-by-step explanation:
multiplying both the equation
We know that in an isosceles triangle the two base angles are equal so let's get the sum of both
54+54 = 108
So the vertex angle equals
180-108
72°
Answer:
B

Answer:
8 to 40, 2/10, 6:30
Step-by-step explanation:
8:40 -> 8 / 8 : 40 / 8 -> 1:5 WORKS
3:20 -> 3 / 3 : 20 / 3 -> Doesn't work
2:10 -> 2 / 2 : 10 / 2 -> 1:5 WORKS
6:30 -> 6 / 6 : 30 / 6 -> 1:5 WORKS
2:9 -> 2 / 2 : 9 / 2 -> Doesn't work
5:20 -> 5 / 5 : 20 / 5 -> 1:4 -> Doesn't work
Answer: 8 to 40, 2/10, 6:30
