Question

line xy and MN intersect at o .if angle POY =90°and a:b=2:3 find c​

Answer 1

Step-by-step explanation:

Hey!

___________________

When we move towards centre of earth, the mass is equally distributed in all directions.

The mass beneath you = Mass in front of you = Mass behind you

Thus, all the gravitational forces applied cancel each other and acceleration due to gravity (g) at centre of earth on centre of earth becomes zero (0).

Answer 2

Figure:-

Given:-

• XY and MN intersect at O.
• <POY = 90°
• a:b = 2:3

To Find:-

• Find c ......?

Solutions:-

Let the common ratio between a and b be x.

a = 2x and b = 3x

XY is a straight line, rays OM and OP stand on it.

Therefore,

⟹ <XOM + <MOP + <POY = 180°

⟹ b + a + <POY = 180°

⟹ 3x + 2x + 90° = 180°

⟹ 5x + 90° = 180°

⟹ 5x = 180° - 90°

⟹ 5x = 90°

⟹ x = 90°/5

⟹ x = 18°

• a = 2x = 2 × 18° = 36°
• b = 3x = 3 × 18° = 54°

MN is a straight line. Ray OX stand on it.

⟹ b + c = 180° ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀(Linear pair)

⟹ 54° + c = 180°

⟹ c = 180° - 54°

⟹ c = 126°

Additional Information:-

• Straight line = Angle which measures 180°.

• Supplementary Angle = The two angle are supplementary, if there sum are 90°.

• Complementary Angle = The two angle are complementary, if these sum are 90°.
