Answer:

<h3>The answer is option A</h3>

Step-by-step explanation:

Angles in a triangle add up to 180°

Since it's a right angled triangle one of it's angles is 90°

So for angle F we have

F + 25 + 90 = 180

F = 180 - 115

<h3>F = 65°</h3>

To find GH we use tan

tan 25 = FG / GH

FG = 7m

tan 25 = 7 / GH

GH = 7 / tan 25

<h3>GH = 15.0 m</h3>

To find FH we use sine

sin 25 = FG / FH

sin 25 = 7 / FH

FH = 7/sin 25

<h3>FH = 16.6 m</h3>

Hope this helps you

Whats the parallel equation of y=1/3x-2 goes through point (0,6)
loris [4]

You know that two lines are parallel if they have the same slope, so the new line will also have slope

m=\frac{1}{3}

Because the equation of the given line is written in the form

\begin{gathered} y=mx+b \\ \text{Where} \\ m\colon\text{slope of the line} \\ b\colon\text{ y-intercept} \end{gathered}

Then, you can use point slope equation, which is

\begin{gathered} y-y_1=m(x_{}-x_1) \\ \text{Where} \\ (x_1,y_1)\colon\text{ point through which the line passes.} \\ m\colon\text{slope of the line} \end{gathered}

So,

\begin{gathered} (x_1,y_1)=(0,6) \\ \text{ And you have} \\ y-y_1=m(x_{}-x_1) \\ y-6=\frac{1}{3}(x-0) \\ y-6=\frac{1}{3}x-0 \\ y-6=\frac{1}{3}x \\ \text{ Add 6 to both sides of the equation} \\ y-6+6=\frac{1}{3}x+6 \\ y=\frac{1}{3}x+6 \end{gathered}

Therefore, the equation of the line that is parallel to y=1/3x-2 and goes through point (0,6)​ is

y=\frac{1}{3}x+6

5w=5×10 to the second power
torisob [31]
Hey there!


5 x w = 10 to the second power . . .

10 x 10 = 100

5 x 100 = 500

5 x w = 500

500 = 5w

w = 100 <-------

Hope this helps you.
Have a great day!
