Cant really show you how to do it but the graph would start at the y axis at (0,-2) then from there each point would move to the left 4 and up 7 or back 4 and down 7. It would form a straight line.

I’ll give brainly The measure of ABC = 180°.
PolarNik [594]

Answer:

y=37

Step-by-step explanation:

the addition of the 3 angles is 180°

then 40 + y +29 +2y  = 180

        69 + 3y =180

        3y  = 180 -69

        3y= 111

        y =111 ÷ 3

        y = 37

NEAD HEALP SOLVING THIS QUESTION

Answer:

obtuse triangle, because 22^2 + 51^2 = 54^2

Step-by-step explanation:

Well an easy way to start it off would be to draw it.

When you draw it out, it makes it easier to see and determine what type of triangle it is so you can use process of elimination.

I've included a picture so you can see.

As you can see, the blue represents the angle that's different than the rest. Since its larger than 90 degrees its an obtuse angel.

Even though there's two acute angels, the triangle is obtuse.

So we can use process of elimination to determine that its not the first two.

Next, to determine if it is obtuse or acute, usually your supposed to use a^2 + b^2 = c^2

So lets do that.

A=AB (22)

B=AC (51)

C=BC (54)

C will always be the largest side.

so lets set it up. 22^2 + 51^2 > 54^2

22^2 = 484

51^2 = 2601

54^2 = 2916

484 + 2601 > 2916

3085 > 2916

The statement is true showing that its obtuse.

If c was equal to a and b then it would be right.

If a and b was less than c then it would be acute.

So the answer would be the last option.

If you ever need more help, don't be afraid to reach out. I hope that helps!
