The y intercept is where the graph crosses the vertical y axis. This happens at 4 on the y axis. We can get more specific to say the location is (x,y) = (0,4). Though we could go for the shorter form because all y intercepts occur when x = 0.
If angle B measures 25°, the approximate perimeter of the triangle is 10.48 units. A right triangle is shown. Angle A is 90 degrees and angle B is 25 degrees.
