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.

<u>Ratios:</u>

  • 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

It's basic subtraction. you subtract 7 1/8 with 4 4/8 by turning one of the one from the seven to 8/8 and add that to 1/8 so you get 9/8. Then 6 9/8 - 4 4/8 = 2 5/8.
