How many triangles are formed by the angles and sides-unique triangle, no triangle, or many triangle

kirill115 [55]

No triangle formed

Solution:

Given data:

One angle is 45°

Another angle is 108°

One side is 7 cm

To find how many triangles are formed for the given data.

Let the unknown side of a triangle be x°.

Sum of all the sides of a triangle = 180°

45° + 108° + x° = 180°

⇒ x° = 180° – 45° – 108°

⇒ x° = 27°

There is no such angle can be formed with 27° in the given image.

Hence there is no triangle can be formed.

If you're going to use technology (Brainly) to solve this problem, you might find you get a quicker answer using the technology of your graphing calculator.

It is often convenient to cast the problem in the form f(θ) = 0. You can do that by adding 1 to both sides of the equation.

$4\sqrt{2}\cos{(\theta)}+4=0\\ \cos{(\theta)}+\dfrac{1}{\sqrt{2}}=0\qquad\mbox{divide by $4\sqrt{2}$}\\ \cos{(\theta)}=\dfrac{-\sqrt{2}}{2}\qquad\mbox{subtract $\dfrac{1}{\sqrt{2}}$}\\\\ \theta=\{\dfrac{3\pi}{4},\dfrac{5\pi}{4}\}\qquad\mbox{determine the corresponding angles}$
