Answer:

10x

Step-by-step explanation:

From my understanding, I believe you are trying to ask what the answer to both numbers combined is. This is just like 4+6 (10), just add an "x" (10x) in the front. I hope this helped!

Consider a triangle with two sides that

AURORKA [14]

9514 1404 393

Answer:

C) 14 cm

Step-by-step explanation:

A triangle solver can quickly show you the third side is 14 cm.

The law of cosines can be used for this purpose. If the given sides are 'a' and 'b', and the third side is 'c', then that law tells you ...

c² = a² +b² -2ab·cos(C)

c² = 7² +11² -2·7·11·cos(100°) ≈ 196.74

c ≈ √196.74 ≈ 14.03

The length of the third side is about 14 cm.
