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:
< 4, - 7 >
Step-by-step explanation:
- w - z
= - < - 5, 3 > - < 1, 4 > ← multiply each component in w by - 1
= < 5, - 3 > - < 1, 4 > ← subtract corresponding components
= < 5 - 1, - 3 - 4 >
= < 4, - 7 >
Answer:
that is the answer

Answer:
I think it is the daughter
Step-by-step explanation:
only because she is only 115 m away from home plate itself and the father is 132m away which is going to take some for the sound waves to travel and for anyone to hear . Also if you don't believe me, more of an explanation is ...
Kilometers are 1,000 times larger than meters. The meter is the base unit for measuring length or distance in the metric system.
132 km x 1,000 = 132,000m and 115 is already in meters now i think that is simple enough of an explanation. Your welcome. I know I'm right
