Is 6,7,13 a right triangle

Mathematics

1 answer:

Scilla [17]2 years ago

7 0

Answer:

Step-by-step explanation:

For a right triangle, according to the Pythagorean Theorem, the 2 sides squared must equal the hypotenuse squared. ( $a^{2} +b^{2} =c^{2}$ )

The hypotenuse is the longest side so $13^{2}=169$

$6^{2}=36\\7^{2}=49$

36 + 49 does not equal 169

The marker cost 1/3 as a pen.The pen cost 1/3 as much as the book.The book cost 1/3 as much as the game. The price of the marker

creativ13 [48]

Let the price of game, marker, pen and book be $w, x, y and z.

$x = \frac{1}{3} y$
$y = \frac{1}{3} z$
$z = \frac{1}{3} w$
$x = \frac{1}{3} y \\ x = \frac{1}{3} ( \frac{1}{ 3} z) \\ x = \frac{1}{3} ( \frac{1}{3} ( \frac{1}{3} w) \\ x = \frac{1}{27} w$

Find sin(b) in the triangle.<br> A.4/3<br> B.3/5<br> C.3/4<br> D.4/5

DerKrebs [107]

The value of $\sin \beta$ in the given triangle ABC is $\dfrac{4}{5}$ . Option D is correct.

<h3>What are the trigonometric ratios?</h3>

Trigonometric ratios are the ratio of sides of a right angled triangle. There are 6 types of trigonometric ratios: sin, cos, tan, cosec, sec, and cot.

Sine trigonometric ratio is the ratio of perpendicular (side opposite to the angle) to the hypotenuse.

In the given figure, the side opposite to the angle $\beta$ is AC = 4 and the hypotenuse is AB = 5.

So, the sine ratio will be equal to,

$\sin \beta=\dfrac{4}{5}$

Therefore, the value of $\sin \beta$ in the given triangle ABC is $\dfrac{4}{5}$ . Option D is correct.
