Question

4. PQRS is a parallelogram in which angle Q and angle R
are in the ratio 7:11. Find all the angles.​

Answer 1

Answer:

Step-by-step explanation:

INA PARALLELOGRAM ADJACENT ANGLE SUM 180°

SO Q AND R ARE ADJACENT ANGLES

LET Q AND R ARE = 7X AND 11X

7X + 11X = 180°

18X = 180°

X   = 180/18 = 10°

S0 7X = 7 * 10 = 70°  

     11X = 11*10 = 110°

P = R

Q = S    [ OPPOSITE ANGLE ARE EQUAL IN PARALLELOGRAM

SO ALL ANGLES ARE 70°,70°,110° AND 110°
