Answer:
46 degrees
Step-by-step explanation:
They will be forming a right triangle.
long leg is the height of Lyra. 22 meters high from the entrance.
short leg is the distance of Donna. 50 meters from the entrance.
We need to solve for the hypotenuse or the range of communication.
a² + b² = c²
22² + 50² = c²
484 + 2500 = c²
2,984 = c²
√2,984 = √c²
54.63 = c
The range of communication for the two radios is 55 meters.
I believe it’s 50% because you divide 8/2 and that’s 4, and 4+8=12
X = 2i, -2i (I’m sorry if it does come back as wrong but it’s the only answer I got)
Answer:
7 years
Step-by-step explanation:
Use the formula I=Prt
Convert 4% to a decimal. 4% = 0.04
1428 = 5100(.04)t
1428 = 204t
1428/204 = 204t/204
t = 7 years
