Question

I need some help plz!!
An observation tower in a national park is shown. The ladder is 3 feet away from the post and the post has a length of 12 feet.

THE PICTURE IS ATTACHED BELOW!!!!!!

What type of triangle does the ladder form with the ground and the post?

acute scalene

acute isosceles

right scalene

right equilateral

I am pretty sure it is not a right triangle but....what is it???

Answer 4

Okay, I see it. It looks like a Right Scalene.

Answer 5

Alright thanks, how do you figure that out though?

Answer 6

You're welcome, and a equilateral triangle has three equal sides, A Isosceles has two equal sides and a scalene has no equal sides. So in the picture you see that there is a right angle and no equal sides.

Answer 7

Does that make sense ?

Answer 8

Yes it does, thank you . Thank you ! Do you think you could help me with a couple more?

Answer 9

No problem :)
And Yes.

Answer 10

Thelma completed the steps shown to construct an obtuse triangle. P and R represent two vertices of the triangle.
Which point could represent the third vertex of the obtuse triangle?

Y, because it lies beyond the arc.

W, because the measure of angle WPR is greater than 90 degrees. (I think it's this answer, since it would have to be on the side of the W to make an obtuse angle, but I'm not sure.)

V, because the measure of angle VPR is less than 90 degrees.

X, because it lies on the perpendicular line.

Answer 11

2.W, because the measure of angle WPR is greater than 90 degrees.

An obtuse triangle has one obtuse angle as an interior angle. The measure of <WPR has to be greater than 90 degrees

Answer 12

Thank you !

Answer 13

You're welcome. :)

Answer 14

Haley constructed the obtuse isosceles triangle RST as shown in the figure below.

(I chose A is that correct?)

What is the error in Haley’s construction?

A. She plotted point T to the right of the perpendicular line.

B. She did not ensure that side RS is congruent to side RT.

C. She plotted two vertices on the arc.

D. She did not plot point R on the arc.

Answer 15

Yes, that is right. Because the distance from any point on the arc to the center is going to be equal. So the only problem is the obtuse part, which she could fix by putting T on the left hand side of the perpendicular line.

Answer 16

Yay!!! I have another confusing one:

Look at triangle PQR. Segment PN is 9 inches.
Which statement is true?

The length of segment PO is 3 inches.

**The length of segment PO is 6 inches.** I think it's B.

The length of segment RN is 4.5 inches.

The length of segment ON is 4.5 inches.

Answer 17

correct

Answer 18

thank you !
