The area of a rectangle is 33 m-, and the length of the rectangle is 5 m less than twice the width. Find the dimensions of the r

denis-greek [22]

Answer:

x = 9.25

y = 13.5

Step-by-step explanation:

area = 33

let length be y and width be x

2x - 5 = y

area of rectangle = length * breadth

(2x-5)(x)=33

2x²-5x=33

2x²-5x-33=0

solving quadratic equation

x = 9.25

y = 13.5

Answer:

$\frac{\sqrt{17} }{7}$

Step-by-step explanation:

Using the Pythagorean identity

sin²x + cos²x = 1, then

sinx = $\sqrt{1-cos^2x}$

Note that ( $\frac{4\sqrt{2} }{7}$ )² = $\frac{32}{49}$

sinΘ = $\sqrt{1-(32/49)}$

= $\sqrt{\frac{17}{49} }$ = $\frac{\sqrt{17} }{7}$
