In this triangle, the product of sin b and tan c is , and the product of sin c and tan b is

Answer

part 1 = c/a

part 2 = b/a

Sine is the ratio of opposite to hypotenuse respect to as a given angle while tangent is the ratio of opposite to adjacent lengths of a given angle.

Part 1

Sine = opposite/hypotenuse

SinB = b/a

Tangent = opposite/adjacent

TanC = c/b

SinB × TanC = b/a×c/b

                       = c/a

Part 2

SinC = c/a

TanB = b/c

SinC×TanB= c/a×b/c

                   = b/a

just sum

10 + 10 = 20
