What is the cosine law?

The squared of the size of any solitary side of either a triangle is equal, by the cosine rule, to the total of the squares of the lengths of the other two sides, times by the cosine of something like the angle they are a part of.

Let the triangle ΔABC, then the cosine law is given as,

c² = a² + b² - 2 a·b cos C

In ΔABC, if the length of sides a, b, and c are 3.5 centimeters, 5.5 centimeters, and 6 centimeters respectively. Then the measure of the angle ∠C is given as,

6² = (3.5)² + (3.5)² - 2 · (3.5) · (3.5) cos C

Simplify the equation, then we have

6² = (3.5)² + (3.5)² - 2 · (3.5) · (3.5) cos C

36 = 12.25 + 12.25 - 24.50 cos C

11.5 = - 24.50 cos C

cos C = - 11.5 / 24.5

C = 117.99

The measure of the angle ∠C to two decimal places will be 117.99°.

Two sporting goods stores are having discount sales on basketballs. • At one store, a basketball is on sale for 20% off the regular price of $24.95. • At the other store, the same kind of basketball is on sale for 25% off the regular price of $25.80. What is the difference between the sale prices of the two stores?

Answers

Store A has 20 percent off which translates too 4.99 off 24.95 which leaves the total at 19.96.

Store B has a 25 percent off which translates too 6.45 off of 25.80 which gives you the total of 19.35 .

Store B has a better sale on prices of the basketball.

Answer:

The answer is A) $0.61

Which of the following best defines the quantities that should be measured to find Andy driving speed?The quantity of time measured in hours depends on the quantity of distance measures in miles
The quantity of distance measures in miles depends on the quantity of time measures in hours
The quantity of time measured in minutes depends on the quantity of speed measured in feet
The quantity of speed measured in feet depends on the quantity of time measured in minutes

Answers

I believe the answer is B.) The quantity of distance measures in miles depends on the quantity of time measures in hours. This is because when trying to find speed a person must know the distance and the time that the object/person traveled that distance which the time is mostly measured in hours.
I hope I helped!

I think its B because you measure distance on the road in miles, you don't measure how far you went by hours. And the quantity of time does not measure in miles, but hours.

Ezra is participating in a marathon walk for charity. He knows he can walk 3 miles in 45 minutes. At the rate, how long will it take Ezra to walk 26 miles

Answers

so 3 miles in 45 minutes
make ratio or fraction
3:45 or 3/45=1/15
ratio=1:15
so 26 miles
for every 1 mile, add 15 minutes
26 miles so
26 times 15=390 minutes or 6.5 hours or 6 hours and 30 minutes
