Question

plz answer plz answer​

Answer 1

Step-by-step explanation:

Since it is isosceles triangle, y = 48°

then,

48°+y+9x-6°=180°

48°+48°+9x-6°=180°

9x+ 90°=180°

9x=180°-90°

9x=90°

x=10°

Answer 2

Answer:

y=48 (angle corresponding to equal sides)

48+48+(9x-6)° = 180° [ angle sum property]

or, 96 + (9x-6)°= 180°

or, (9x-6)°= 180°- 96°

= 84°

therefore x = (84+6)°/9

= 10°
