Answer:
13) 8.6
Step-by-step explanation:
To find the side length, use a trig function to solve for x.
You have the adjacent side and hypotenuse to the angle. Use the cosine function since its ratio is adjacent over hypotenuse.
This means Cos 52 = x / 14. Solve for x.
Cos 52 = x / 14
14* Cos 52 = x
8.6 = x
Notice y° and y° and 50°, are all three angles in a flat-line, namely "linear angles", and since a flat-line is always 180°.
The mean is 73.44<span>
</span>You could've found this by adding up all the values in the data set, then dividing by how many numbers were in the data set!
66+81+60+72+79+83+60+92+68 = 661
661 ÷ 9 = 73.44
i believe the correct answer is 163
Answer:
1,383
Step-by-step explanation:
15x11+(29x42)
