Setting up a right triangle, the 100 would be the hypotenuse, the 45 would be the angle of elevation, and you're looking for the opposite side.
Sin 45 = x/100
100sin45 = x
100 * ✓(2)/2 = x
50 ✓2 =x
x = 50✓2 ft
Answer: 1. 2nd endpoint (24,-18) 2. 2nd endpoint: (-19,4)
Step-by-step explanation:
1. 
= 7 x = 24
= -6 y= -18
2nd endpoint: (24,-18)
2. 
= -10 x= -19
= 2 y= 4
Answer: 105 of them are hummingbirds.
Step-by-step explanation:
I there are a total of 350 birds then 30% o 350 will give the number o hummingbirds.
350 of 30%
350 * 0.3 = 105
Answer:
x equals 10
Step-by-step explanation:
All triangles have 180 degrees
The bottom left angle is a right angle and is therefore 90°
That leaves us with x+8x=90°
9x=90°
x=10°
Hundreds and tens are easy to add, so we can round 203 to 200, and 222 to 220.
220+200=420, so
222+203 rounds to about 420
