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)

sas (side angle side)

aa(angle angle)

sss(side side side)

aa you find two angles because it will always add up to 180

sss find all sides
