Answer 1

Looking at your diagram you see that \(\bf{\angle TRY}\) is vertical from \(\bf{\angle QRW}\) this means by `Vertical Angle Theorem` they are congruent.

\(\large\bf{\angle TRY = \angle QRW}\)

Substitute.

\(\large\bf{x+16=4x-5}\)

What does x equal?

Answer 2

7

Answer 3

Correct so `x = 7`.

This answer part A.

~~

Now to find \(\bf{\angle TRY}\) you would plug in `7` into its equation.

\(\large\bf{ \angle TRY = 7 + 16}\)

What does \(\bf{\angle TRY}\) equal?

Answer 4

23

Answer 5

Correct. So that answers part B.

Now if you view your diagram you see that \(\bf{\angle TRQ}\) lies on `the same line` as \(\bf{\angle TRY}\) this means that these two angles are `supplementary` meaning they create a `180 degree angle`.

So to find \(\bf{\angle TRQ}\) you would subtract `180 and 23`.

\(\large\bf{\angle TRQ=180-23}\)

Answer 6

What does \(\bf{\angle TRQ}\) equal?

Answer 7

im doing 3 things at once, im sorry.
<TRQ=157

Answer 8

It's okie, take your time.

You are correct. That answers part C.

Your question says `A-D` but I only see from `A-C` for this problem.

Answer 9

give me a moment to look through the doc

Answer 10

According to my teacher its only A-C not A-D, there was a typo

Answer 11

ah i see, on to the next one, give meh a sec

Answer 12

I'm still trying to think of a good explanation for 2, so let's do 3.

There are 3 known postulates in which you can prove a triangle: `AAS, SAS, and SSS`

Lets look at the first one you can see that we have a pair of angles that are congruent, as well as congruent right angles, we are not given any other info, since aren't told about any sides being equal to each other by length we do not have enough info so it would be `NA`.

Try and do the others and ill check them if they are right for you.

Answer 17

As I said before and deleted, I only do my own math. I do not do it for others.

Answer 20

only question 3 and 4

Answer 21

3 has three angles as congruent, not sides. 4 has three sides as congruent.

Answer 22

Oh I was referring to the 3rd and 4th figures in your last posted screenshot. This is why I encourage people to not have so much in one question, it is quite unorganized and can be confusing.

Answer 23

I am not sure you understand these laws. I would encourage you to review them in your lesson or here: https://www.onlinemathlearning.com/prove-triangles-congruent.html
