Answer:
x=12
Step-by-step explanation:
The two angles make a straight line, which is 180 degrees
10x-20 +6x+8 = 180
Combine like terms
16x -12 = 180
Add 12 to each side
16x-12+12 = 180+12
16x =192
Divide by 16
16x/16 = 192/16
x =12

Answer:
20 units
Step-by-step explanation:
Let the equal sides of the triangle be x.
Then the third side will be (x+5) units
Since the perimeter is 50, we have:

We simplify to get:

This implies that:


Divide both sides by 3 to get:

The length of the third side is:
15+5=20
