Enter a range of values of x
igomit [66]

Answer:

-5.

Step-by-step explanation:

We know that if two corresponding sides of two triangles are equal, then third sides of the triangles depend on angle between equal sides.

Angle opposite to larger side is larger.

Since, 14 < 15, therefore

2x+10

2x

2x

x          ...(1)

We know that, angle can not not negative.

2x+10>0

2x>-10

x>-5        ...(2)

From (1) and (2), we get

-5

Therefore, the range of values of x is -5.
