Q7.Which of the following sets of angles can be the angles of a triangle?

$\tt\red{ANSWER}$$\tt\blue{::}$

As we know that sum of angles of a $\tt\red{Triangle}$ is $\rm\red{180}$$\rm\blue{Degrees}$.

So, look for set of angles with sum of 180 degrees.

So we look that option $\tt\pink{c).}$$\tt\orange{50,30 \:and\: 100}$has sum of $\tt\purple{180}$$\mathfrak\green{degrees}$.

So,$\bf\red{Option\:C}$$\sf\blue{:is\: correct}$

Answer 2

Step-by-step explanation:

c) 50°, 30°, 100°

We known that sum of all three angles of a triangle is 180°.

So,

50°+30°+100°=180°
