Given the following:

Like terms are those terms which have same variable to the same power.

Take common from and

then;

we have;

Therefore, the simplified form of is

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

a
