Answer 1

Answer:

Step-by-step explanation:

i.) x+135=180  (angles on a straight line)

   x=180-135

   x=55

ii.)let the reflex angle be z

   z+126=360  (sum of reflex angles)

   z=360-126

   z=204

iii.)y=135  (adjusent angles)

   

Answer 2

Answer:

(i) 75

(ii)234

(iii)25.5

Step-by-step explanation:

(i) x+135°=180°

x=(180-135)°

x=75°

(ii) PQR + reflex PQR=360°

Let reflex PQR=a

126+a=360

a=360-126

a=234°

(iii) Given, x=QRS

=>QRS=y

QRS+x+y+a=360°

2y+75+234=360

2y=360-309

2y=51

y=25.5°

Hope it helps!
