Answer:

Relations trigonometric are special measures a triangle rectangle ( a triangle with an angle measuring 90 or ). Remember that the two sides of a right triangle that form the right angle are called the legs, and the third side (opposite the right angle) is called the hypotenuse.

Las relaciones trigonométricas son medidas especiales de un triángulo rectángulo (un triángulo con un ángulo de 90 o). Recuerda que los dos lados de un triángulo rectángulo que forman el ángulo recto se llaman catetos y el tercer lado (opuesto al ángulo recto) se llama hipotenusa.

Trigonometric functions are commonly defined as the quotient between two sides of a right triangle, associated with its angles. Trigonometric functions are functions whose values are extensions of the trigonometric reason concept in a right triangle plotted in a unit circumference (radius unit).

Solving a right triangle (ROUND TO THE NEAREST TENTH)

Kay [80]

Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180 for B

B = 180° - (90 + 40)° = 180° - 130° = 150°

--------------------------------------------------------------

sin40° = $\frac{opposite}{hypotenuse}$ = $\frac{a}{21}$

Multiply both sides by 21

21 × sin40° = a, thus

a ≈ 13.5 ( to the nearest tenth )

--------------------------------------------------------------

cos40° = $\frac{adjacent}{hypotenuse}$ = $\frac{b}{21}$

Multiply both sides by 21

21 × cos40° = b, thus

b ≈ 16.1 ( to the nearest tenth )

Determine whether the relationship between the circumfrance of a circle and its diameter is a direct variation. If so, identify

kipiarov [429]

Answer:

The relationship between the circumference of a circle and its diameter represent a direct variation and the constant of proportionality is equal to the constant $\pi$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y=kx$

where K is the constant of proportionality

In this problem we know that

The circumference of a circle is equal to

$C=\pi D$

therefore

the relationship between the circumference of a circle and its diameter is a direct variation and the constant of proportionality is equal to the constant $\pi$

Write this ratio as a fraction in simplest form without any units. 5 weeks to 10 days

faltersainse [42]

1/2. If you take out the units you're left with 5 to 10 or 5/10. 5 is half of 10 therefore the simplest form would be 1/2.

Which of the following is a solution of y > |x| - 5? a.(4, -1)<br> B.(-1, -4)<br> C.(-4, 1)

Savatey [412]

Fill your inequality in with the y and x provided and then do the math. (4, -1) would fill in like this (I will use brackets to indicate absolute value symbols, since there are none in the equation editor): $-1\ \textgreater \ [4]-5$ The right side is in fact equal to the left side so that's not the answer. For (-1, -4): $-4\ \textgreater \ [-1]-5$ and these are also equal. Let's try C now (-4, 1): $1\ \textgreater \ [-4]-5$ . The absolute vale of -4 is 4 so 4 - 5 = -1 which is, in fact, less than 1. So C is our answer.
