Answer:
c = 126°
Step-by-step explanation:
Line OP is perpendicular to line XY. Hence ∠POY = ∠POX = 90°
∠POX = ∠POM + ∠MOX
90° = a + b ….(1)
Since a and b are in the ratio 2 : 3 that is,
a = 2x and b = 3x ….(2)
Substituting (2) in (1),
a + b = 90°
2x + 3x = 90°
5x = 90°
x = 90°/5 = 18°
a = 2x = 2 × 18°
a = 36°
b = 3x = 3 × 18°
b = 54°
Also , ∠MOY= ∠MOP + ∠POY
= a + 90° = 36° + 90° = 126°
Lines MN and XY intersect at point O and the vertically opposite angles formed are equal.
∠XON = ∠MOY
I hope you find the answer useful.
Sure, I can help you with that.
Given:
* Lines XY and MN intersect at O.
* Angle POY = 90°
* a : b = 2 : 3
To find:
* c
Solution:
1. Since lines XY and MN intersect at O, we know that ∠POY = ∠MOX.
2. We also know that a : b = 2 : 3, so ∠POY = 2x° and ∠MOX = 3x°.
3. Since ∠POY + ∠MOX = 90°, we can substitute in the expressions we found for each angle to get 2x° + 3x° = 90°.
4. Simplifying the right side of the equation, we get 5x° = 90°.
5. Dividing both sides of the equation by 5, we get x° = 18°.
6. Since ∠MOX = 3x°, we know that ∠MOX = 3 × 18° = 54°.
7. Finally, we know that ∠MOX + ∠NOX = 180°, so 54° + c = 180°.
8. Subtracting 54° from both sides of the equation, we get c = 180° - 54° = 126°.
Therefore, c = 126°.
I hope this helps! Let me know if you have any other questions.
