Question

Find the measure of angle CBA

Answer 1

@SunshineGirl The sum of the interior angle measures of a triangle is 180.

So, 4x + 7 + 11x -9 + 32 = 180

Solve that equation for x.

Then, substitute the value of x into 11*x -9 to get the value of <B.

Answer 2

Ok, I did it but I really don't think I did it correctly because I'm bad at following equations. I got 28.51

Answer 3

@SunshineGirl Did you get 28.51 for the angle B or for the value of x?

Answer 4

For the value

Answer 5

What did you get for x in this equation:

4x + 7 + 11x -9 + 32 = 180

Answer 6

3.41

Answer 7

4x + 7 + 11x -9 + 32 = 180

15x + 30 = 180

15x = 150

@SunshineGirl Try again for x using 15x = 150.

Answer 8

So, x=10?

Answer 9

So then the angle would be 101?

Answer 10

Let's see.


(11*10) - 9 = 110 - 9 = 101 ---> I got the same as you. @SunshineGirl

Answer 11

Ok! Thank you!

Answer 12

You're welcome.

Answer 13

What do I do from this point on though? How do I find the rest of the angle?

Answer 14

The instruction says this: Find the measure of angle CBA.

We did that so I guess this problem is finished. Check the instructions in your book to make sure.

Answer 15

I thought we only found angle B
