Step-by-step explanation:

4x+3+63+90=180°

4x+156=180°

4x=180-156

4x=24°

x=24

4

x=12° ans

hope it is correct.

Answer:

6!

Step-by-step explanation:

I'm not as sure about this answer, but I got it like this!

We know that a triangle adds up to 180. Two of our given measurements are 90 and 63. Adding those together we get 153. To solve for x, you'd have to subtract that from 180.

From there, you get 27! That's the answer to the equation, but not the value of x.

4 time 6 ( which is x) is 24, plus 3 is 27, so we know that x is 6!

I hope this helped, and made sense!!
