Answer:
The total number of train tickets Aaron can buy=4
Step-by-step explanation:
a). Determine first expression
Let the number of each mode of transport be as follows;
bus ticket=b
train ticket=t
b). Determine the second expression
Let the total cost be expressed as shown;
total cost=(cost per bus ticket×number of bus tickets)+(cost per train ticket×number of train tickets)
where;
total cost=$520
cost per bus ticket=$64
number of bus tickets=b=3
cost per train ticket=$82
number of train tickets=t
replacing;
(64×3)+(82×t)=520
192+82 t=520
82 t=520-192
82 t=328
t=328/82=4
t=4
The total number of train tickets Aaron can buy=4
∠ROT=160°
∠SOT=100°
Now ∠SOR= ∠ROT - ∠SOT
∠ SOR = 160°-100°
∠ SOR =60°
It is given that measure of angle ROQ to equals the measure of angle QOS equals the measure of angle POT.
∠SOQ + ∠QOR = 60°
But ∠SOQ = ∠QOR
2∠SOQ=60°
∠SOQ=60°÷2
∠SOQ =30°
Also ∠POT=∠SOQ=∠ROQ=30°
