There are two probabilities of the solution. First if 80° acts as one of the leg angles, second if 80° acts as the vertex angle.
FIRST PROBABILITY
If 80° is one of the leg angles, then the other angle would be 80° too, because iscosceles has two congruent angles on the leg.
Find the vertex angle
the sum of interior angles in a triangle is 180°
vertex angle + angle on the leg + angle on the leg = 180°
vertex angle + 80° + 80° = 180°
vertex angle + 160° = 180°
vertex angle = 180° - 160°
vertex angle = 20°
The interior angles are 80°,80°,20°
SECOND PROBABILITY
If 80° is the vertex angle, we should find the value of the two leg angles. The two legs has congruent angles.
Find the leg angles
the sum of interior angles in a triangle is 180°
leg angle + leg angle + vertex angle = 180°
2 × leg angle + vertex angle = 180°
2 × leg angle + 80° = 180°
2 × leg angle = 180° - 80°
2 × leg angle = 100°
leg angle = 50°
The interior angles are 80°, 50°, 50°

Answer:
It will cost $72 Justice to fence in his garden.
Step-by-step explanation:
Total length of the fencing around the garden = 24 feet
Cost of fencing per inch = $0.25
Now, as we know 1 foot = 12 inches
⇒ 24 feet = 24 x 12 inch = 288 inches
⇒ 24 feet = 288 inches
Hence, the total length of fencing = 288 inches.
Now, Total cost of Fencing
=Total length of fencing x Cost of fencing par inch
= 288 inches x ($0.25)
= $ 72
or, the total cost of fencing = $72
Hence, it will cost $72 Justice to fence in his garden.
