Question

in given figure find the value of x​

Answer 1

Answer:

Step-by-step explanation:

soluation:-

first figure

The value of x (∠ BOC ) = (180° - ∠AOC )

                                        = (180° -35° )

                                         =145°

∴ ∠BOC is 145°

second figure

The total value of ∠POR or ∠ROP is 180° (straight angle )

Let, ∠ROQ +∠POQ =180°

or, 5x +4x =180°

or, 9x =180°

or, x=20

∴ ∠ROQ = 5X =(5×20)=100°

∴ ∠POQ = 4X = (4×20)=80°
