Question

Help please, I can’t figure out what the answer is or where to start

Answer 1

x = 10

Explanation:

in this kind of equation the two inside angles added together equals the outside angle

so

4x + 10 + 50 = 9x + 10

then combine like terms

4x + 60 = 9x + 10

and subtract like terms

50 = 5x

lastly divide

x is 10
