Question

in the figure. <B = 90° ,<A = <C and BC = 10cm then find the value of tan 45°​

Answer 1

Answer:-

B = 90° , A = C

So,

A = C = 45°

Hence, Tan Theta = Perpendicular/Base

Tan Theta = ab/bc

Tan Theta = bc/bc (ab = bc)

Tan theta = 1

Tan theta = Tan 45°

Theta = 45°

Then,

Tan 45° = 1
