You need to use the Law of Cosines:
AC² = AB² + BC² - 2·AB·BC·cos(b)
Therefore, you get:
AC = √(90² + 80² - 2·90·80·cos(50)
=√5243.86
= 72.4 in
Now you can sum up all the sides in order to find the perimeter:
AB + BC + AC = 90 + 80 + 72.4 = 242.4 in
The correct answer is A) 242.4 in
Answer:
the answer is no
Step-by-step explanation:
first i added the price of the CD to how much Sara has won already, so that i know exactly how much Sara has left, which is $875. then i added the cost of the dvd player to see if it was more than 999, and it was. with the dvd player the total would be $1,014
It will hit the ground after 3.499 seconds.
To solve this you first have to find the value of h(0) in this equation. That is the height from which it was dropped.
You can input any of the points into the equation and solve for the missing part. You will get 60 for the height.
The use the quadratic formula to see that it reaches the ground after 3.499 seconds.
Yes it is because the 2 pair of lines are parallel to each other
16 6th graders went on the field trip and 16 5th graders went on the field trip so that makes 32 students all together which means 32% of the students went on the field trip
