Ipatiy [6.2K]

Answer: 11.4 feet of the ground

Step-by-step explanation:

You would use sin to get the answer. So it'd be sin(72) = x/12

Once you get the sin you would multiply it by the 12 to get the x by itself and that's your answer.

It would be sin because the question is asking for that side, and it's across the 72, making it the opposite side, the side that is across from the 90 degrees is always the hypotenuse and you have a number for that side and sin uses the opposite and hypotenuse

PLEASE HELPP!!!!!<br>what is the slope of the line?<br><br>-3<br><br>1<br><br>0<br><br>undefined
marysya [2.9K]
Answer: -4

The formula for slope is rise/run. This means that between two points, you have to see the distance going up and down/ left and right.

Looking at points (0,-1) and (3,-1), you can see that the height difference is 4 units. This means that the rise is 4.

rise/run

4/run

Left and right, the difference is only one unit.

4/run

4/1

4

This graph is also negative, so let’s add that in.

-4

This is your answer! I know it wasn’t one of the options you provided, but I’m pretty sure that this is the answer.

Hope this helps comment below for more questions :)

I'll focus on problem 19 and problem 22

============================================================

Problem 19

Answers:

  • x = 87
  • x+15 = 102

-------------------------------

Explanation:

The horizontal lines are parallel. Note the arrow markers along the interior portion of the lines. These similar markers tell us how the lines pair up to be parallel to one another.

Since the horizontal lines are parallel, this means the angles in question are congruent. They are corresponding angles.

x+15 = 102

x = 102-15

x = 87

Which leads to

x+15 = 87+15 = 102

============================================================

Problem 22

Answer: y = 27

-------------------------------

Explanation:

We have a pair of alternate exterior angles. They are congruent due to the parallel lines.

Let's solve for y.

7y-55 = 3y+53

7y - 3y = 53+55

4y = 108

y = 108/4

y = 27

In the given figure, BAC = 90° and ABC = 45°. Prove that: AB = AC. ​
Amiraneli [1.4K]

Answer:

<h2>By angle sum property:</h2>

BAC+ABC+BCA=180°

90°+45°+x=180°

135°+x=180°

x=45°=BCA

<h2>since BCA=ABC=<u> </u>45° each </h2><h2>therefore,</h2>

AB=AC \\ (isosceles \: triangle \:  \\ theorem)
