30 POINTS! "A triangle with the side lengths of these numbers CAN exist: 9, 3, and ____?

Mathematics
1 answer:
Kisachek [45]3 years ago
3 0

Answer:

Let the third side be x

We know that

Sum of two sides of a triangle must be greater than the third side

So,

9 + 3 > x

12 > x (1)

Also, difference of two side of triangle must be smaller than the third side

9 - 3 < x

6 < x (2)

From 1 and 2 we concluded

6 < x < 12

The length of third side would lie between 7 to 11

<h3>Answer: B) 10.3</h3>

Work Shown:

cos(angle) = adjacent/hypotenuse

cos(20) = x/11

11*cos(20) = x

x = 11*cos(20)

x = 10.336618828645

x = 10.3

Make sure your calculator is in degree mode.
