Answer:

96°

Explanation

Given problem:

Find the value of x in the diagram;

Given that lines a and b are parallel lines and transversal c cuts through them;

the two given angles are said to be equal and alternate angles;

So;

99 = x + 3

x = 99 - 3 = 96°

The value of x is 96°

If g(x) is the inverse of f(x), what is the value of f(g(2))? a.–6 b.–3 c.2 d.5

Answers

The value of the function f(g(2)) is 2. Option C

How to determine the value

First, we need to know that functions are described as expressions showing the relationship between two variables.

These variables are the dependent and independent variable.

When g(x) is the inverse of f(x), it means that g(f(x)) = x for all x in the domain.

In this case, we want to find f(g(2)), which means we need to find the value of f when the input is g(2).

Since g is the inverse of f, g(2) should equal the value of x such that f(x) = 2.

So, f(g(2)) = f(x) where x = 2

Step-by-step explanation:

78% of 3 feet is inches.

Answers

3 feet converted to inches is 36 inches. We need to find 78% of 36 inches. To do that you need to divide 78 by 2.7 which is 28.8 inches.(30 if you round it.)

Final answer:

To find 78% of 3 feet in inches, you can convert 3 feet to inches (giving 36 inches), then find 78% of this by multiplying by 0.78. This gives us 28.08. Therefore, 78% of 3 feet is 28.08 inches.

Explanation:

To find 78% of 3 feet in inches, first convert the feet to inches. Since 1 foot equals 12 inches, 3 feet is equivalent to 36 inches. Now, to find 78% of these 36 inches, multiply 36 by 0.78 (which is the decimal equivalent of 78%). This gives us 28.08. Therefore, 78% of 3 feet is 28.08 inches.
