3. In a triangle, two angles have measures of 45° and 85. What is the measure of the third angle in
this triangle?

Triangles always have 180°, split in some manner between the three angles. With two of the three angles given, you can set up a relatively simple equation, where the third angle is assigned to the variable x:

45°+85°+x=180°

130°+x=180°

x=50°

yes   because as the functions are graphed they eventually will intersect unless otherwise
