In the diagram of right triangle GFE below, altitude FD is drawn. Which of the
following ratios is equivalent to sin E?
answers: GD/DF, GF/GE, DE/FD, FE/GE
Answers
The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. The correct option is B.
What is Sine (Sinθ)?The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. it is given as,
Sin(θ) = Perpendicular/Hypotenuse
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The hypotenuse is the longest side of the triangle.
In the ΔGEF, the value of Sin(E) is,
Sin(E) = GF/GE
In the ΔDEF, the value of Sin(E) is,
Sin(E) = FD/FE
Hence, the correct option is B.

You move left 5 units. You end at (-1, 5). Where did you start?
Answers
Answer:
(4,5)
Step-by-step explanation:
Hello!
If you move 5 units to the left, you change the x-value in (x, y) by -5.
Let the original x-value be x:
x - 5 = -1x = 4The original x-value is 4. Since you didn't change the y-value (up/down), you can keep the same y-value for the coordinate.
The original point was at (4,5)
Answer:
You started at (4, 5)
Step-by-step explanation:
The first number of coordinate pair is x. you started at the right and THEN moved the the left, as stated in the question. So -1 + 5 is 4.
So you started at (4, 5)

The measure of the angle m1 is 110 degrees
How to determine the measure of angle m1?The measures of the arcs are given as:
Arc 1 = 130
Arc 2 = 90
The measure of the angle is calculated using:
Angle = 0.5 * (Arc 1 + Arc 2)
So, we have:
Angle = 0.5 * (130 + 90)
Evaluate
Angle = 110
Hence, the measure of angle m1 is 110 degrees

The correct steps are:
2x - y = 18
2x - (4x + 2) = 18
2x - 4x - 2 = 18
-2x - 2 = 18

The function f(x) is shown on the graph.
On a coordinate plane, a curved line with 3 arcs, labeled f of x, crosses the x-axis at (negative 2, 0), (negative 1, 0), (1, 0), and (3, 0), and the y-axis at (0, negative 6).
What is f(0)?
0 only
–6 only
–2, –1, 1, and 3 only
–6, –2, –1, 1, and 3 only
Answers
By using the description of the graph, we conclude that f(0) = -6 only.
The correct option is the second one.
What is f(0)?
Here we want to know the value of the function when evaluated in 0. Remember that the points on the graph of the function are of the form:
(x, f(x)).
Now, in the description of the graph you say:
"... and the y-axis at (0, negative 6)."
So we know that the graph passes through (0, -6), which means that when evaluated in 0, the function is equal to -6.
So the correct option is the second one: –6 only

a) x<7x<7
b) x>−21x>−21
c) x<−21x<−21
d) x>7x>7
Answers
The solution to inequality is less than the negative of 21. Then the correct option is C.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The inequality is given below.
−(1/3)x + 10 > 17
Then the solution to the inequality will be
−(1/3)x + 10 > 17
−(1/3)x > 17− 10
−(1/3)x > 7
When the sign is changed then the equality sign also changed.
(1/3)x < −7
x < − 21
The value of x is less than the negative of 21.
Thus, the correct option is C.
