Question

3. In the given figure, l || m and p is the
transversal. If angle1 and angle2 are in the ratio
1:2, find the measure of each of the angles.​

Answer 1

Answer:

Correct answer is 60

Step-by-step explanation:

L1 & L2 are in ratio 1:2

let L1=k

L2=2k

L1+L2=180 ∘

(∵sum of angles on a straight line = 180 ∘ )

⟹k+2k=180 ∘

⟹3k=180 ∘

⟹k=60 ∘

⟹L1=60 ∘

,L2=120 ∘

L2+L3=180 ∘

(sum of angles on a straight line = 180 ∘ )

⟹L3+120 ∘

=180 ∘

⟹L=60 ∘

L3=L7(∵ l & m are parallel, ∴correspondingangles)

L7=60 ∘
