Find the area of the shaded region where s = 18. Round your answer to two decimal places.

Answer:

SinA=3/5

CosA=4/5

TanA=3/4

Step-by-step explanation:

first we have to find what side length bc is using the Pythagorean triple formula a^2+b^2=c^2 or c^2-b^2=a^2

20^2-16^2=144 the square root of 144 is 12 so side length bc=12

so sin is opposite/hypotenuse

the opposite of angle a is 12 and the hypotenuse is 20 so sinA is 12/20 or 3/5

cos is adjacent/hypotenuse

the adjacent of angle a is 16 and the hypotenuse is 20 so cosA is 16/20 or 4/5

tan is the opposite/adjacent

the opposite of angle a is 12 and the adjacent is 16 so tanA is 12/16 or 3/4

Answer:

Paulo = 3m - 5

Step-by-step explanation:

m = number of quarters Marie has

The number of quarters Paulo has is 3 times 5 fewer than the number of quarters Marie has

3 times number of quarters Marie has = 3 * m

= 3m

5 fewer than the number of quarters Marie has

3m - 5

Paulo = 3m - 5

Well, since there is no image I thought I would provide what a rectangle would probably look like in your case. The rectangle can be split into half parts 4 ways.

1. We can split it the hotdog way, or staright down the rectangle (drawing provided down below)

2. We can split it the Hamburger way, again drawing is provided.

3. We can split it from the top-left corner to the bottom-right, and the opposite way around.

Answer:

Model B has 6 shaded sections

Step-by-step explanation:

The question is not complete. The complete question should be in the form:

Victor has 2 fraction models. Each is divided into equal sized sections the models are shaded to represent the same fraction. Model A is divided into 6 sections and 3 sections are shaded. Model B is divided into 12 sections. What do you know about the number of sections shaded in Model B? Explain your answer.

Solution:

The fraction modeled by model A is given by the ratio of shaded sections to  the total number of sections.

That is Fraction of model A = number of shaded sections / total number of sections.

Hence:

Fraction of model A = 3 / 6

Since model B and Model A are equivalent, the number of shaded sections in Model A is given by:

number of shaded sections in model B/ total number of sections in model B =  Fraction of model A

number of shaded sections in model B / 12 = 3 / 6

number of shaded sections in model B = 12 * 3/6

number of shaded sections in model B = 6

y=1

Answer:  (2,3)

====================================================

Explanation:

The intersection point of the two lines is where the solution point is located.

The x coordinate of that intersection point is a bit smaller than x = 2, but when rounded to the nearest whole number, we would get to x = 2.

At the same time, the y coordinate of the intersection point is a bit above y = 3, which rounds to this value when rounding to the nearest whole number.

So that's how we get to (2,3)

Answer:

Yes

Step-by-step explanation:

To find out if it's a function, check if any of the y values repeat. If they don't, it's a function. :)

Answer:

B. 120° degrees

Step-by-step explanation:

Inscribed angle ABC = 60°

Arc AC = 2 * < ABC (Relation between arc and inscribed angle)

Arc AC = 2 * 60°

= 120°

Answer:

Because, Angle ABC is incribed in arc AC .

We know that it's 2times than angle ABC.

THEREFORE, 60 × 2 = 120

Answer:

1. Well, to cross multiply them you multiply the numerator in the first fraction times the denominator in the second fraction, then you write that number down. ... The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater.

2. Cross multiplying fractions to find a missing numerator or denominator for equivalent fractions works because it is a shortcut for rearranging to isolate the variable.

Answer:

D

Step-by-step explanation:

x+17 = 4x-34

-3x = -51

x = 17

17+17= 34

The bottom two are equal so 34, 34

A triangle adds up to 180

180- 68 = 112

So the top is 112

After solving the equation for all three angles of a triangle, the angles are 34, 112, and 34. Hence, option C is correct.

The basic polygonal shape of a triangle has three sides and three interior angles. It is one of the elementary objects in geometry and is represented as follows. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.

As per the given angles of a triangle in the question,

Let angle A = 6x + 10  (i)

Angle B = x + 17 and,   (ii)

Angle C = 4x - 34  (iii)

The submission of all angles will be equal to 180°.

(6x + 10) + x + 17 + 4x - 34 = 180

11x = 187

x = 17

Substitute the value of x in equations to find the angle,

A = 6(17) + 10 = 112

B = 17 + 17 = 34

C = 4(17) - 34 = 34.

These are the angles obtained
