Question

Pls help me :(


Solve for x

Answer 1

x=-3

Explanation:

To start off, you're going to want to know and understand that all the angles of triangle equal 180 degrees.

Now that we know a triangle equals 180 degrees, lets make an equation. This is equation can be 55+54+74+x=180.

Now, lets combine the like terms in the equation. The equation now becomes 183+x=180.

From here, we subtract 180 from both sides, which would get us x=-3.

To double check that this is correct and that it works, you can plug in the -3 where the x would be.

I hope this helped!! Let me know if you have any further questions.

Answer 2

x = -3

Explanation:

To answer this question, you should first remember that the inside angles of a triangle will always add up to 180 degrees. Therefore, we can make an equation and solve it form there:

55 + 54 + (x + 74) = 180

We add like terms:

109 + (x + 74) = 180

Continue adding like terms:

183 + x = 180

Next, we dubtract to siolate the "x" variable:

x = -3

Hope this helps :)
