Answer:
A
Step-by-step explanation:
First, we need to find the unknown angle of the triangle.
40 + 20 = 60
180 - 60 = 120
So the unknown angle is 120.
Then, we can use the law of sines to create a proportion.
sin(120)/8 = sin(40)/a
Then, we can simplify this.
a is about 5.9, or answer choice A.
2,-4 is you awnser. good day to you
Hello!
The appropriate unit to measure the horizontal distance between the two ends of the loop is B, feet. Why?
Choice A, miles, seems not proportionate because rollercoaster loops wouldn't be a mile long.
Choice C, centimeters, is 0.01 of a meter, and that's way too small.
Finally choice D, inches, imagine a quarter, that's how long an inch is.
So therefore, your choice is correct, which is choice B.
Answer:
The answer is c. 8 hours
Step-by-step explanation:
Since her battery dropped 25% in 2 hours then for it to drop 100% would take 8 hours.
25%+25%+25%+25%= 100%
so with this logic
25%= 2 hours
2+2+2+2=8
Hoped this helped !
