I think the truss is just one of those triangles whose sides are 3ft, 3ft, 3ft so its perimeter is
Answer: 9 feet
Answer:
78
Step-by-step explanation:
∠A + ∠B + ∠C = 180 { Angle sum property of triangle}
42 + ∠B + 60 = 180
∠B + 102 = 180
∠B = 180 - 102 = 78
In similar triangles, corresponding angles are congruent.
∠S ≅ ∠B
∠S = 78°
5x10-27=$23
5 = amount of bills, 10= dollar bills, 27= cost of toy, 23= cost leftover
