Answer:
Swap the direction of the inequality
Step-by-step explanation:
Anytime you multiply or divide by a negative number in an inequality, you flip the symbol so > turns into <
The midsegment is half the length of the base. So the base = 2*4 = 8 in.
Since it is an isosceles triangle, the other two sides are equal in length.
Perimeter = sum of two equal sides + base = 20 in.
2x equal side + 8 = 20
equal side = 12/2 = 6
Each of the equal sides = 6"
