Answer:
14
Step-by-step explanation:
The law of cosines is a² = b²+c²-2bc(cos A).
We will use s in place of a, since it is the unknown side. This makes b and c 8 and 9.
Angle A will be the angle opposite side a, or in this case side s. This makes it 111.
This gives us
s² = 8²+9²-2(8)(9)(cos 111)
s² = 64+81-2(8)(9)(cos 111)
s² = 145-144(cos 111)
s² = 196.605
Take the square root of each side:
√(s²) = √(196.605)
s = 14.02 ≈ 14
Answer:
154
Step-by-step explanation:
Primes less than 20 are:
2, 3, 5, 7, 11, 13, 17, 19
Possible combinations that add up to 20 are:
2 + 5 + 13
2 + 7 + 11
The products are:
2 × 5 × 13 = 130
2 × 7 × 11 = 154
So the largest possible product is 154.
