That would be true because the adjacent side to B is 4 and the hypotenuse is 5 and the formula for cos b is adjacent/hypotenuse
Hope this helps!

Answer:
x= 17 and y=20
Step-by-step explanation:
4x- 3y= 8-------1
5x-4y= 5-------2
Subtracting 2 from 1
5x-4y= 5
-4x+3y=-8
x-y=-3----------3
From 3 we have x= y-3-------4
Putting 4 in 1
4(y-3) -3y= 8
4y - 12 -3y= 8
y= 8+12
y=20------------5
Putting 5 in 2
5x - 4(20)= 5
5x=5+80
5x= 85
x= 17------6
Answer:
Length: sqrt13 + 4
Width: sqrt13
Step-by-step explanation:
Denote the width as x, then the length is x+4. The area of the rectangle will be x(x+4), and the perimeter will then be 4x +8. Hence, you can write the equation x(x+4) - 5 = 4x+8. Solving, you get x = sqrt13.
