3. triangle abc has angle measures as shown.
(a) what is the value of x? show your work.
(b) what is the measure of angle c? show your work.

angle a = 38 degrees
angle b = x
angle c = x + 2

Value of X= 70

Angle measure of C is 72 degrees

Ok, so this is how I got it

Although this is geometry, you have to use some pre-algebra.

Every single triangles angle measures adds up to 180 degrees.

In order to find X, the equation is:

m of angle a + m of angle b + m of angle c= 180

Plug in your numbers

38 + X + X + 2 = 180

Add your like terms,

X + X= 2x and 38 + 2= 40

Now our eq looks like this: 2x + 40 = 180

This is where the pre algebra comes in

Subtract 40 from both sides because the opposite of adding 40 is subtracting 40

40 - 40= 0 and 180 - 40 = 140

Now our eq looks like: 2x = 140

Since 2 and X are being multiplied we do the opposite which is divide 2 and 140

140 divided by 2= 7-0

X = 70

Now you know the value of x, so just plug it in.

38 + 70 + 72 = 180??

If it equals 180 you are correct (it does )

I am so sorry it is long and if it is confusing I am sorry too, but it is kind of hard to explain thru typing, but I hope it helps in some way :)

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
