Question

In triangle ABC ,rightangled at B. If tanA=1/1 find the value of sinAcosC+CosAsinC​

Answer 1

Answer:

1

Step-by-step explanation:

the right side is a summary of finding sin,cos,tan,cot. if tana=1, you have a 45-45-90 triangle, which has 1-1-sqrt2 values. after calculating the sin and cos values, you multiply and fing the sum.

1/sqrt2 * 1/sqrt2 + 1/sqrt2 * 1/sqrt2 will give you 2/2, which is 1.
