Question

find value of x!

Answer 1

I'm not 100% on this, but I believe every triangle has to add up to 180 degrees.

So one is 40 degrees, one is x degrees, and the other is (5x + 14) degrees.

So you would have to add all that up to equal 180.

So basically - 40 + x + (5x + 14) = 180

This is how you would start it up anyway.

Now you have to solve for x.

Answer 2

40 + x + (5x + 14) = 180

first you must subtract 40 from both sides

So you would get: x + (5x + 14) = 140

Answer 3

ok

Answer 4

Then I believe you have to subtract the 14 from both sides as well? (I think)

So you would get x + 5x = 126

Answer 5

You can combine like terms to get
6x = 126
So now you would have to divide 6 from both sides.
