What angles can form a triangle

1 answer:

Dimas [21]3 years ago

5 0

Answer:

The right triangle: The right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees... The two sides of the triangle that are by the right angle are called the legs... and the side opposite of the right angle is called the hypotenuse.

Assume that the terminal side of thetaθ passes through the point (negative 12 comma 5 )(−12,5) and find the values of trigonomet

zmey [24]

Answer:

$\sin \theta = \dfrac{5}{13}$ and $\sec \theta = -\dfrac{13}{12}$

Step-by-step explanation:

Assume that the terminal side of thetaθ passes through the point (−12,5).

In ordered pair (-12,5), x-intercept is negative and y-intercept is positive. It means the point lies in 2nd quadrant.

Using Pythagoras theorem:

$hypotenuse^2=perpendicular^2+base^2$

$hypotenuse^2=(5)^2+(12)^2$

$hypotenuse^2=25+144$

$hypotenuse^2=169$

Taking square root on both sides.

$hypotenuse=13$

In a right angled triangle

$\sin \theta = \dfrac{opposite}{hypotenuse}$

$\sin \theta = \dfrac{5}{13}$

$\sec \theta = \dfrac{hypotenuse}{adjacent}$

$\sec \theta = \dfrac{13}{12}$

In second quadrant only sine and cosecant are positive.

$\sin \theta = \dfrac{5}{13}$ and $\sec \theta = -\dfrac{13}{12}$

Lines m and n are parallel. find the value of x.<br> A. 15<br> B. 20<br> C. 65<br> D. 115

torisob [31]

Answer:

Option B, x = 20

Step-by-step explanation:

<u>Step 1: Make an equation</u>

The values of 65 degrees and (3x + 5) are equal.

65 = 3x + 5

<u>Step 2: Subtract 5 from both sides</u>

65 - 5 = 3x + 5 - 5

60 = 3x

<u>Step 3: Divide both sides by 3</u>

60 / 3 = 3x / 3

<em>20 = x</em>

<em />

Answer: Option B, x = 20
