The sum of the degree measures of any triangle is 180. in a particular isosceles triangle the degree measure of the vertex angle is 112. find the measure of each base angle

34

Step-by-step explanation:

Each of the base angles = x

x + x + 112 = 180                Subtract 112 from both sides. Simplify the left side.

2x + 112 - 112 = 180 - 112    Simplify

2x = 68                              Divide by 2

2x/2 = 68/2                       Simplify

x = 34

Each of the base angles = 34 degrees.

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4
