Answer: OPTION C.
Step-by-step explanation:
1. To solve this problem you must apply the Pythagorean Theorem, which is shown below:
Where a is the hypotenuse, and b and c are the legs of the triangle.
2. When you solve for one of the legs and substitute values, you obtain that the result is:
Answer:
14, or 4/14 if you're looking for the ratio.
Step-by-step explanation:
Simple addition, although maybe man-hours is some advanced concept and I'm wrong, in which case I'm sorry.
<h3><u>
The value of y is 1.6</u></h3><h3><u>
The value of x is 4.5</u></h3>
By elimination:
2x + 5y = 17
6x - 5y = 19
<em><u>We can add the second equation to the first in order to isolate one variable.</u></em>
(2x + 5y) + (6x - 5y)
8x = 17
<em><u>Because we added the left side, we have to add the right side here as well.</u></em>
17 + 19 = 36
8x = 36
<em><u>Divide both sides by 8</u></em>
x = 4.5
We can plug this value back into the original equation to find the value of y.
2(4.5) + 5y = 17
9 + 5y = 17
<em><u>Subtract 9 from both sides.</u></em>
5y = 8
<em><u>Divide both sides by 5.</u></em>
y = 1.6
Answer:
∠DGF
Step-by-step explanation:
Supplementary angles are those that add up to 180 degrees. Or, if no specific degrees are given (like in this case), supplementary angles are simply those that constitute a perfect line.
Looking at the diagram, the lines are CF, AD, and BE. Our angle is ∠CGD. Notice that both angles ∠DGF and ∠CGB are possible supplementary angles to ∠CGD because ∠CGD + ∠DGF make a line and ∠CGD + ∠CGB make a line.
We can just choose any of the two: say, ∠DGF.
