Select All Equations That Can Be Used To Solve For 0. If You Have Time, Can You Please Explain How You

Answers

Answer 1

Answer:

B and D are correct.

Step-by-step explanation:

First, we find the length of ALL the sides using the Pythagorean Theorem.

16² + b² = 20²

256 + b² = 400

b² = 144

[tex]\sqrt{144}[/tex] = 12

Now, we know that sine is opp/hyp, cosine is adj/hyp, and tangent is opp/adj.

A is incorrect because that's supposed to be cos. B is correct because that is indeed cos. C is incorrect. D is correct. E and F are incorrect because it's supposed to be sin.

Don't know if any of that made sense. All you need to do is remember the difference between sine, cosine, and tangent.

Answer 2

Answer:

The answer is B and D.

Step-by-step explanation:

Length of ladder AC = 20 feet

Height of the highest point of the ladder from ground AB = 16 ft

By Pythagoras theorem,

AC² = BC² + AB²

BC² = AC² - AB²

BC = √(20)^2-(16)^2

     = √400-256

     = √144

     = 12

Now, Sinθ = opposite side/hypotenuse = AB/AC

                 = 16/20

Cosθ = adjacent side/hypotenuse = BC/AC

         = 12/20

Therefore, A and D are the correct options.

You're very welcome! ;)

Which is a quadrilateral that could have one pair of parallel sides and one pair of sides that are not parallel?

Answers

Answer:

trapezoid.

Step-by-step explanation:

A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs

Characteristics of a trapezoid

It has 4 vertices and edges

If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram

Area of a trapezoid = [tex]\frac{1}{2}[/tex] x (sum of the lengths of the parallel sides) x height

Perimeter =  sum of lengths of sides of a trapezoid

Volume of a Cylinder: In geometry, a cylinder is a three-dimensional shape with a circular base, a circular top and straight sides. It is the solid figure that you get when you rotate a rectangle about one of its sides. In most cases when we talk about the volume of a cylinder, we are talking about how much liquid it can hold.

The strictly correct way of saying it is "the volume surrounded by a cylinder" - the amount of liquid it holds. But many textbooks simply tell "the volume of a cylinder" to mean the same thing.Step-by-step explanation:
