In ΔFGH, the measure of ∠H=90°, GF = 53, HG = 28, and FH = 45. What ratio represents the sine of ∠G?
andrew11 [14]

we have been given that in ΔFGH, the measure of ∠H=90°, GF = 53, HG = 28, and FH = 45. We are asked to find the ratio that represents the sine of ∠G.

First of all, we will draw a right triangle using our given information.

We know that sine relates opposite side of right triangle with hypotenuse.

\text{sin}=\frac{\text{Opposite}}{\text{hypotenuse}}

We can see from the attachment that opposite side to angle G is FH and hypotenuse is GF.

\text{sin}(\angle G)=\frac{FH}{GF}

\text{sin}(\angle G)=\frac{45}{53}

Therefore, the ratio \frac{45}{53} represents the sine of ∠G.

What is the slope of a line perpendicular to the line whose equation is 10x + 6у –84. Fully simplify your answer.​
mixer [17]

Answer:

The slope is 3/5.

Step-by-step explanation:

I am assuming you mean

10x + 6y = 84

6y = -10x + 84

y = -5/3 x + 14.

So the slope of this line is -5/3 and the slope of a line perpendicular to it is

-1 / -5/3 = 3/5.

PLS HELP ME ASAP FOR THIS!! (MUST SHOW WORK!!) + LOTS OF POINTS!!

You can see that angle TQV = 90 degrees
Angle RQV = 136 degrees

Angles RQV and  UQV are supplementary and equal 180 degrees since they form a straight line. Therefore angle UQV = 180 - 136 = 44 degrees.

TQU + UQV = 90 degrees. Therefore, TQU = 90 - UQV.

90 - 44 = 46 degrees for angle TQU.
