Answer:
18°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
90° + 72° + ∠? = 180°
162° + ∠? = 180° ( subtract 162° from both sides )
∠? = 18°
Answer:
x²
Step-by-step explanation:
Let "d" represent the divisor (what goes in the blank). Then you have ...
... (x²y)/d = y
Multiplying by d gives ...
... x²y = yd
And dividing by y gives the desired value:
... x² = d
The divisor is x².

Answer:
80cm^3
Step-by-step explanation:
16/4 = 4
This means that the scale factor = 4
320cm^3 = Volume of BB
BB/4 = Volume of SB
320/4 = 80
Therefore, the volume of the small box = 80cm^3.
