Question

in triangle abc angle a = 30 degree b= 90 find side ab if CA= 10cm​

Answer 1

Answer:

Therefore answer is

AB = 5 √3 cm.

Answer 2

Answer:

Here in triangle ABC

A = 30° B = 90°

A+B+C = 180°

30 + 90 + C = 180°

C = 60°

by 30°-60°-90°

AB = 1/2 × CA ------(side opposite to 30°)

AB = 1/2 × 10

AB = 5cm
