The sides of a right triangle are 3,4 and 5 the tangent of angle A is

What is the value of r of the geometric series?

Given ab and cb are tangents of p, and m =10°. what is the measure of abp?

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
