Question

If 3A = 90°, find sinA​

Answer 1

Answer:

The answer will be 1 /2.

Step-by-step explanation:

We have given that;

                              3A = 90°;

                              A = 90°/3;

                              A = 30°

Hence, sinA = sin30°;

Now according trigonometric ratio table;

                               sin30° = 1 / 2;

Hence, the answer will 1 / 2.

That's all.
