Question

please fast tell me these all threee answers I am requesting maths​

Answer 1

13. y = 80° (Vertically opposite angles)

y+50°+x = 180° (Angle Sum Property Of a ∆)

80°+50°+x = 180°

x = 180°-130°

x = 50°

12. SP = 21600

Gain% = 8%/

CP = 100/(100+gain%) × SP

CP = 100/(100+8) × 21600

CP = 100/108 × 21600

CP = 2160000/108

CP = ₹ 20,000

Answer 2

={(100/108)×21600}

={2160000/108}

=Rs.20000
