Question

figure PQ is parallel to our and peace transversal if angle 1 and angle 2 is 3 is to 2 then the what is the value of angle 3 and angle for r​

Answer 1

Answer:

Explanation:

let ∠a=2x and ∠b=3x

∠a+∠b=180  

∘

 (adjacent angles on straight line are supplementary)

⇒2x+3x=180  

∘

 

⇒5x=180  

∘

 

⇒x=  

5

180  ∘

 

​  

=36  ∘

 

Now ∠b=3x=3×36  ∘

=108  ∘

 

∠c=∠b        (Vertically opposite angles)

⇒∠c=108  

∘

 

m∣∣n and l is transversal  

∴∠h=∠c      (corresponding angles)

⇒∠h=108
