Answer:
Provided in the picture below.
Step-by-step explanation:
Provided in the picture below.
∠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°

Step-by-step explanation:
Let the coordinate of the points W, V and R are and
respectively.
The coordinate of the section point, which divides the line joining the two points
and
in the ration
is
and
.
The given ration is,
.
The exact point can be determined by putting the value of the exact coordinate in the above-obtained formula.
