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.
Answer:
74.42
Step-by-step explanation:
(150-86):86*100 =
(150:86-1)*100 =
174.41860465116-100 = 74.42
If 101 use 3/5 for his Artwork, then the space remaining for 102 is:
5/5 - 3/5 = 2/5 (since the whole wall represents 100% or 5/5 or 1)
