One way is to move the 4 to other side so it would be x = 13 - 4 and that's x = 9
Answer:
C
Step-by-step explanation:
hope I'm right sorry if I'm not lol.
First you need to know that the internal angles of a triangle always equals 180°. Therefore:
15+45= 90°
Then since the angles should equal 180, you do:
180-90=90
So the missing angle equals 90°
Binomial is the correct type of polynomial for this problem
