Question

Is this right?

Answer 1

Answer:

Q1.

AC is the greatest side, therefore is hypotenuse. AB and BC are legs.

B is 90 deg as the two legs cross at this point.

Ratios:

• sin = opposite / hypotenuse
• cos = adjacent / hypotenuse
• tan = opposite / adjacent

BC is opposite to A and adjacent to C

AB is adjacent to A and opposite to C

• sin A = cos C = 8/10 = 4/5
• cos A = sin C = 6/10 = 3/5
• tan A = cot C = 8/6 = 4/3
• tan C = cot A = 6/8 = 3/4
