Question

Plz help me i dont understand

Answer 1

Explanation:

The sum of a triangle is 180 degrees so if you add up the 2 to get 102 than subtract it by 180-102 you will get 78 degrees as your remaining answer as k because once you add all of those up you will get 180 degrees which is equivalent to the triangle.

Answer 2

Hello!

The answer is: 78°

Why?

Since the sum of the angles of a triangle must be equal to 180°

Using the given information:

`47+55+k=180\\K=180-102=78`

So, k is equal to 78°

We have an acute triangle since all of the angles are between 0° and 90°

Have a nice day!
