In triangle ABC m

Question

In triangle ABC m<A:m<B:m<C=2:3:4. What is m<C?

I know that A=2, B=3, C=4. And I know you set them to x. So 2x+3x+4X, now what? I know it has to equal something.

The three angles in a triangle sum up to a total.  How many degrees in a triangle?  They all total up to a value which you need to memorize.

radar · Answer

For an example,  a circle adds up to 360 degrees, a square totals up to 360 degrees, a triangle sums up to 180 degrees.

anonymous · Answer

180?

anonymous · Answer

so you set them equal to 180?

radar · Answer

Yes, now I believe you can solve for x, I will standby in case you have further difficulty.

radar · Answer

After solving for x then compute the measure of the angles.

anonymous · Answer

is 20 x?

radar · Answer

Solution for x:        2x + 3x  +  4x = 180

9x = 180
x = 20   

Angle A = 2x = 40 degrees
Angle B  = 3x = 60 degrees
Angle  C = 4x  =  __________?

radar · Answer

Yes x is 20 degrees, but the measures is the values, 2x, 3x, 4x

anonymous · Answer

c= 80?

radar · Answer

Yes note that they will add up to 180 degrees.
