Answer:
x + y are either 2 or 4
Step-by-step explanation:
conclusion x + y = 2 OR 4
Answer:
ac=-3, BC=57 I hope it will help you please follow me
So if we see the first one (8,4) x=8 and y=4
And we see the 2nd one (4,y) x=4 and y=?
We notice that the value of x its been halved. So y varies with x so y value also has to be halved so y= 2
Option A:

Solution:
Given data:
AB = 50, BC = 48, AC = 14
To find the value of sin A and cos A:







Hence option A is the correct answer.
T = 2π√(l/g)
<span>=> T = 2π√[5m/(9.8m/s²)] </span>
<span>=> T ≈ 4,49s </span>
