Answer:

Option A is correct.

Step-by-step explanation:

The height of the rectangular pack is h1 = 4r

The height of the parallelogram = 2r + the height of equilateral triangles with a side of 2r

The height of equilateral triangle with a side of 2r = (side)/2*√3

=(2r)/2 *√3 = r√3

The height of the parallelogram h2 = 2r+r√3 = r(2+√3)

So,the ratio of h1 to h2 is :

4r : r(2 +√3)

Cancelling r we get

Hence, the ratio is  4 : 2 +√3

Answer:

x=29.9 degrees

Step-by-step explanation:

Sides we are given: x and side length of 92.

Angle we are given: angle of measure 18.

Relative to the angle we are given, we have the opposite and adjacent sides, so we use TOA, as O is opposite and A is adjacent.

Tangent 18= x/92

Tangent 18 (92)=x

x=29.9 degrees

Solve the equation for x, where x is a real number (5 points): <br> -2x^2 + 5x + 2 = -3
Juli2301 [7.4K]
Add 3 to both sides so that the equation becomes -2x^2 + 5x + 5 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
                              x = [ -b ± √(b^2 - 4ac) ] / (2a)
                              x = [ -5 ± √(5^2 - 4(-2)(5)) ] / ( 2(-2) )
                              x = [-5 ± √(25 - (-40) ) ] / ( -4 )
                              x = [-5 ± √(65) ] / ( -4)
                              x = [-5 ± sqrt(65) ] / ( -4 )
                              x = 5/4 ± -sqrt(65)/4
The answers are 5/4 + sqrt(65)/4 and 5/4 - sqrt(65)/4..
