Question

A B = 6 cm,
In Right A ABC LB = 90
B C = 8cm, determine sin a and
Sec
С C​

Answer 1

Answer:

AC = 10cm ( by Pythagoras theorem)

sinA= 8/10

secC = 10/8

Answer 2

△ ABC is a right angled triangle.

By Pythagoras theorem,

       AC2=BC2+AB2

=>AC2=62+82

=>AC2=36+64

=>AC2=100

=>AC=100

=>AC=10cm.
