How do you find the product of
-1/5(-2 1/4)

The answer is 9/20

Step-by-step explanation:

So first you gotta convert any mixed numbers into improper fractions

You muipltiy the denominator by the whole number then add that to your numerator, the denomniator stays the same.

so if you follow that it would look like this now

-1/5 (-9/4)

Since we’re multiplying by 2 negatives with each other, its gonna be positive. Multiply it normally from left to right for both the numerator and the denominator

9/20

The length of the line segment EF () is approximately 5 feet.

Let be a Triangle, whose expression derived from the Law of Sines is described below:

(1)

Where:

- Measure of the line segment FG, in feet.

- Measure of the line segment EG, in feet.

- Measure of the line segment EF, in feet.

- Angle at vertex E, in sexagesimal degrees.

- Angle at vertex F, in sexagesimal degrees.

- Angle at vertex G, in sexagesimal degrees.

We can determine a missing length, by knowing the length of a neighboring side and two consecutive angles. If we know that , and , then the measure of the line segment EF is:

The length of the line segment EF () is approximately 5 feet.
