Question

Right angled triangle abc right angle at b sinc=4/3 find cosc,tanc

Answer 1

Answer:

• cosc=4/3
• tanc=4/4=1

Step-by-step explanation:

sinc=opp/hyp

=4/3

by Pythagoras theorem

3^2= 4^2 + BC^2

12 = 16 + BC^2

BC^2 = 16 - 12

BC^2 = 4

then cosc= adj/hyp

=4/3

then tanc= opp/adj

=4/4

=1
