Answer:

120 degrees

Step-by-step explanation:

Remember that the interior angles of a triangle always add up to 180 degrees. We know that two of the angles (45 and 15) add up to 60 degrees. Now we just have to subtract the 60 degrees we have from the 180 degree total in order to get the measure of the missing angle.

180 - 60 = 120

Therefore... the answer is 120 degrees

How do i know if a system of equation has infinite number of solutions
Vlad [161]
A system of equations has an infinite number of solutions when after solving the system, you end up with a true statement.

For example, let’s say you solve a system of equations and your result is 5=5. 5=5 is a true statement, but it doesn’t tell us anything about the x or y value solutions to the system. So because we’re only left with 5=5, there are infinite solutions to the system.
