Step-by-step:
The tetrahedron is a triangular pyramid with equilateral triangles on each face.
2.4 hours or 2 hours and 24 minutes represents

of a clock.
The easiest way to find this is to divide 12 by 5 since there are twelve hours on a clock.
I got the 24 minutes by multiplying 60(minutes there are in an hour) by .4 and got 24.
Answer:
each side 5
Step-by-step explanation:
with 2 equal internal base angles, we know this is an isosceles triangle
this being isosceles also tells us that the 2 opposite sides are also equal
Therefore: x + 2 = 3x - 4
solving for x
x - 3x = -4 -2
-2x = -6
x = -6 ÷ -2
× = 3
substituting x:
x +2 = 3 + 2 = 5
3x-4 = 9 - 4 = 5
