Question

in triangle ABC,right angled at B, AC=14 cm and BC=7 cm then find the angle C. ​

Answer 1

Answer:

angle c is equal to 60°

Step-by-step explanation:

Let the angle C be X

We know that ABC is a triangle which is right angled at B

AC = 14cm

BC = 7cm

So here we can easily trigonometry

so COS X = base / hypotenuse

if we put the values

COS X = 7/14

COS X = 1/2

We all know that COS X is 1/2 when X is equal to 60°

so the angle C is equal to 60°.

Answer 2

Answer:

In a triangle ABC, angle B = 90°, BC = 7cm and AC = 14cm, then determine angle A and angle C.
