Find X
5x
A) 11
C) 2
B) -1
D) -2

A) 11

Step-by-step explanation:

there are 180 degrees in a triangle. so, i added 47 and 78 together. that got me 125. i subtracted that from 180, in order to find the remaining angle.

it was 55 degrees, so i divided 55 by 5 in order to see what that was. whatever number that is was going to be x. it turned out to be 11.

hope this helps! xoxo

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
