Answer:
P=106
Step-by-step explanation:
A=a2
P=4a
Solving forP
P=4A=4·702.25=106
The beginning of the line segment starts at 5, and ends at 9.
Therefore,
5 - 9 = 4
The length of the segment is 4.
the answer is 3.279604223
Answer:
Im prety sure the lenghths double aswell. But it also means that the width has doubled.
Step-by-step explanation:
We are asked to solve for the value of cos C on which given side measurements are enumerated below:
AB = 9
BC = 40
CA = 41
Solving for the value of cos C, we will apply Law of Cosines such as the solution is shown below:
cos C = BC² + CA² - AB / (2*BC*CA)
cos C = 40² + 41² - 9² / (2*40*41)
cos C = 0.97561
The answer for the value of cos C is "0.97561".
