What is the perimeter of triangle JEG?
60 units
65 units
70 units
75 units

Answer:
60
Step-by-step explanation:
We are given a figure with several given expressions:
EK = x + 5
KJ = x +5
FG = 2x
GH = 3x - 5
Assuming that the triangle is equilateral:
equate GH = FG
3x - 5 = 2x
solve for x
x = 5
therefore, one side of the triangle:
x + 5 + x + 5 = 20
and the perimeter of the equilateral triangle is
3*one side = 3 * 20 units
Thus, Perimeter = 60 units. <span />

Answer:
10
Step-by-step explanation:
one interior angle in a pentagon is 108^o.
5 interior angles are 540^o.
If we add 12+7+16+9+10, we get 54x=540^o
That means x=10
