Answer:
Step-by-step explanation:
this is a 45-45-90 triangle. The angle opposite the 45° angle is also 45°.
HI = HJ because this is an isosceles triangle.
Use the cos function to find the length of HJ:
cos Ф = adj / hyp or adj = (hyp)(cos Ф).
1
Here we have adj = HI = HJ = 4√5 cos 45° = 4√5 · -----
√2, or 4√5 / √2
4√10
This last result simplifies to ----------
2
or 2√10 (answer)
The length of side HJ and that of HI is 2/√10.
344.75 I did the math lol not that hard tbh
Answer:
The correct answer is option A. r
Step-by-step explanation:
From the figure we can see a circle and a parallelogram.
The circle is divided into a small sectors and these sector then arranged into a parallelogram.
The base of the parallelogram is half the circumference.
The height of parallelogram is equal to the radius of the given circle. Here radius is 'r'.
Therefore the correct answer is option A. r
