a= 8.6
Step-by-step explanation:
just plug it into a calculator, it's easier. the square root of 47 is 6.85565
Answer:
It's B
Step-by-step explanation:
When you graph B, that's what you get
The relationship that their ratios of sin x and cos y share is that they are of equal ratio: sin x = cos y = 4/5
<h3>Recall the Trigonometry Ratios</h3>
- SOH represents sin ∅ = opposite/hypotenuse
- CAH represents cos ∅ = adjacent/hypotenuse
- TOA represents tan ∅ = opposite/adjacent
Thus, given the right triangle as shown in the picture attached below, let's find sin x and cos y.
sin x = opp/hyp = 4/5
cos y = adj/hyp = 4/5
This implies that sin x = cos y, therefore the relationship that their ratios of sin x and cos y share is that they are of equal ratio: sin x = cos y = 4/5

Answer:
Step-by-step explanation:
Rectangle:
Length : Width = 3 : 5
Length = 3x
Width = 5x
Perimeter = 64
2*(length + width) = 64
2*(3x + 5x) = 64 {Add like terms}
2 * 8x = 64
16x = 64 {Divide both sides by 16}
x = 64/16
x = 4
Length = 3*4 = 12 units
Width = 5*4 = 20 units
