Question

what is the method to do

Answer 1

we know that
tan c = perpendicular/base
so here AB = perpendicular and BC = base for angle c

tan c = AB/BC
tan c = 6/8
tan c = 3/4

Answer 2

It is given in the image that in a right angled trianlge, the hypotenuse is 10cm, it's base is 8cm and height's 6cm.

We need to find tanC.

We know that tanθ = opposite side/adjacent side

Here we need to find angle C.

tanC = AB/BC

= 6/8

= 3/4
