Answer:
This is not a right angled triangle.
Step-by-step explanation:
Taking the longest side to be the hypotenuse
45^2+79^2=8266
Square root of 8266=90.91
Hence this is not a right angled triangle.

Answer:
BC =10
AC = 13.661
Step-by-step explanation:
We can use the law of sines to solve this problem
sin C sin B sin A
---------- = ---------- = ---------
AB AC BC
Lets substitute in what we know
sin 30 sin B sin 45
---------- = ---------- = ---------
5sqrt(2) AC BC
We can calculate angle B because all three angles have to add to 180
A+B+C = 180
45+B + 30 = 180
75+B=180
Subtract 75 from each side
75-75+B=180-75
B =105
sin 30 sin 105 sin 45
---------- = ---------- = ---------
5sqrt(2) AC BC
Using cross products and the first and third columns
BC sin 30 = 5 sqrt (2) sin 45
BC * .5 = 5 sqrt(2) * 1/2 sqrt(2)
1/2 BC = 5
Multiply by 2
2*1/2 BC = 5 *2
BC =10
Using cross products and the first and second columns
BC sin 30 = 5 sqrt (2) sin 105
sin 105 is really ugly as an exact answer
.5 AC = 5 sqrt(2) .966
Divide by .5
AC = 5 sqrt(2) .966/.5
AC = 13.661
The answer is B 48 because there are 8 bubbles and you times that by six phone calls
