Step-by-step explanation:
WE KNOW THAT SUM OF ALL ANGLES IN A QUADRILATERAL IS 360°.
LET THE ANGLES BE P=60°,Q=2x,R=3x,S=7x
LET'S TAKE THE SUM
60°+2x+3x+7x=360°
12x=360°-60°
12x=300°
x=300/12
x=25°
NOW WE SHOULD FIND ALL THE ANGLES..
Q=2x
=2×25
=50°
R=3x
=3×25°
=75°
S=7x
=7×25°
=175°
THEREFORE THE MEASURE OF ANGLE S IS 175°

Answer:
∠S = 175°
Step-by-step explanation:
We know that sum of angles of a quadrilateral is 360°
∠P + ∠Q + ∠R + ∠S = 360°
From the given data ∠P = 60°
∠Q , ∠R , ∠S are in the ratio 2 : 3 : 7
Sum of these three angles is 300 [360 - 60]
Let the ratio be 2x : 3x : 7x
2x + 3x + 7x = 300
12x = 300
⇒ x = 25
The angles are 50° , 75° , 175°
∠P = 60°
∠Q = 50°
∠R = 75°
∠S = 175°
