A triangle has the following measurements: B=79 degrees a=5ft

1 answer:

6 0

The law of cosines for this particular situation is b^2 = a^2 + c^2 - 2ac cosB.
Filling in what you know, you have b^2 = 25 + 49 - [2(5)(7)-.1908], which simplifies to b^2 = 74 - 69.8092 which gives you a b^2 value of 4.1908, but you have to take the square root of that so you get a side value for b of 2.05.

Answer:

The product is approximately 5400.

Step-by-step explanation:

9 1/16 rounded to the nearest whole number is 9.

645 3/5 rounded to the nearest hundred is 600.

Multiplying these values gives a product of 9·600 = 5400.

The product is approximately 5400.
