Which of the following is a true statement regarding the quadratic formula form of the solutions to a quadratic equation? The solutions x=4+8<5 decided by 2
are in simplest form.

The solutions x=4+8<5 decided by 2 can be simplified to x= 2=4<5

The solutionsX=4+8<5 devided by 2can be simplified to x= 2 +8<5

The solutions x=
4+8<5 devided by2
must be left in exact form

Cosθ = 3/5

Step-by-step explanation:

Given:

In ∆ ABC.

AB measures = 4

BC measures = 5

CA measures = 3

The angle formed at point C is marked theta

angle A is the right angle

Find attached the diagram from the given information.

We are to find the cosine ratio. To do this, we would apply SOHCAHTOA in trigonometry

Sine ratio: Sinθ = opposite /hypotenuse

Cosine ratio: Cosθ = adjacent/hypotenuse

Tangent ratio: Tanθ = opposite/adjacent

From the diagram,

adjacent = AC

hypotenuse = BC

Using the above formula,

Cosθ = adjacent/hypotenuse = AC/BC

Cosθ = 3/5
