The triangle below is isosceles (two congruent sides). Find the value for x.
one side say x + 3.8 and the other says 16 and then there is nothing at the bottom.

Question

anonymous · Answer

The two sides are congruent means equal measures.
x +3.8 = 16
Solve for x 
x = 16 - 3.8
x = 12.2

anonymous · Answer

the two sides are congruent
therefore the equation wil be...
x+3.8=16
by transposing or combining like terms...transpose 3.8 to the right side of the eqqquation and we will have...
x=16-3.8
i therefore coonclude that the measure of the congruent sides of the isosceles triangle is 12.2
