Answer:
B.) 20 degrees
Step-by-step explanation:
We know that the sum of angles in a triangle is equal to 180, so we can say that 80 + 4x + x is equal to 180. This means that 5x is 100 degrees, meaning that x = 20 degrees. The option with this answer is B.).

Answer:
Pencil: $0.60 Rubber: $0.48
Step-by-step explanation:
Let the cost of a pencil be p and the cost of a rubber be r.
(Equation 1)
(Equation 2)
Divide both sides by 4:
Substitute this into Equation 1:
Multiply both sides by 4:
Divide both sides by 9:
Since r + p = 1.08,
Find the area of the larger rectangle around the shaded shape and subtract the 4 you congruent triangles from it.
