Answer:
1. Naomi spends more
2. Naomi spends $0.59 more
3. total cost is $27.98
4. with 20 dollars Naomi gets $5.72 change back
5. with 15 dollars Demetrius will get $1.30 change back
Step-by-step explanation:
Naomi's total cost:$14.28
0.39+0.79+0.59+(0.79x3)+(0.79x3)+0.39+0.39+6.99=14.28
Demetrius' total cost:$13.70
(0.79x5)+0.79+0.79+(0.59x3)+(0.59x5)+0.59+0.89+0.59+0.59+0.79=13.7

Its one of these but idk witch one sry bout that
An isosceles triangle is a special type of triangle that has two equal sides. Consequently, the two base angles are also equal. Since the interior angles of a triangle should sum up to 180°, the general equation should be
180° = 2*Base angle + Vertex angle
Let the base angle be x. Thus, the vertex angle is equal to
Vertex angle = 4x - 6
Substituting,
180 = 2x + 4x - 6
x = 31°
Vertex angle = 4(31°) - 6
Vertex angle = 118°
