Two angles of a triangle have measures of 30° and 45°. What is the measure of the remaining angle?
Enter the correct answer in the box.

30+45+x=180(sum of all angles of triangle is equal to 180 degree)

75+x=180

x=180-75

x=105

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

combine all like terms then its just a 2 step equation
