Answer:
13. (A, b, C) = (30.66°, 91.042, 25.34°)
14. insufficient information
Step-by-step explanation:
13. The Law of Cosines can help you find the side opposite the given angle. Then that can be used with the Law of Sines to find the other angles.
b = √(a² +c² -2ac·cos(B)) = √(56² +47² -2(56)(47)cos(124°)) ≈ √8288.59
b ≈ 91.042
__
A = arcsin(a/b·sin(B)) ≈ arcsin(56/91.042·sin(124°)) ≈ 30.66°
C = 180° -124° -30.66° = 25.34°
The missing dimensions are (A, b, C) = (30.66°, 91.042, 25.34°).

14. One side and one angle do not define a unique triangle. There is insufficient information to find f.
Answer:
The average of the two boys' points is p=3 is 19.4 points~
Step-by-step explanation:
What you need to do is that you plug p=3 into the expression [(5.4p+5)+(8+3.2p)]/2 and you have:[(5.4*3+5)+(8+3.2*3)]/2= (21.2+ 17.6)/2= 38.8/2= 19.4
Answer:
7 and 11
Step-by-step explanation:
Suppose the numbers are x and y.
So it is given that
x + y = 18
x - y = 4
If we add the equations, we get
2x = 22
So x is 11 and y will be 7
Yes, there was a mistake in applying the distributive property. If you have to perform
you have to multiply both terms in the parenthesis by 3, not just the first one.
So, the correct expansion would be
