Answer:
132cm^2
Step-by-step explanation:
SA of square based pyramid:
SA = 2bs + b^2
b = base
s = slant height
-> 2(6)(8) + 6^2
-> 96 + 36
= 132cm^2
Answer:
the answer is 182
Step-by-step explanation:
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
Q2.
