P is a point on the BC side of the triangle, and PC = Pb. Given that the angle ABC is equal to 45 degrees and the angle APC is equal to 60 degrees, calculate the degree of the angle ACB?

P is a point on the BC side of the triangle, and PC = Pb. Given that the angle ABC is equal to 45 degrees and the angle APC is equal to 60 degrees, calculate the degree of the angle ACB?

Here you are. First of all, ACB is obtuse angle, because acute angle can't be calculated
Make the vertical line of BC from point a, and the vertical foot is v
Let PV = x, and the next step is on the graph. Note that SPRT is the abbreviation of square & nbsp; root, which means that I can't type it,
The final ACB was 98.79 degrees
