Question

3)In figure if line q | liner,
line p is their transversal and if
a=80º find the values of f and g.​

Answer 1

Answer:

. ∠a = 80° [Given]  ∠g = ∠a [Alternate exterior angles]  ∴ ∠g = 80° …..(i)  ii. Now, line q || line r and line p is their transversal.  ∴ ∠f + ∠g = 180°  ∴ ∠f + 80° = 180° [Interior angles]  ∴ ∠f = 180° – 80° [From (i)]  ∴ ∠f = 100°Read more on Sarthaks.com - https://www.sarthaks.com/849372/in-the-given-figure-if-line-line-line-is-their-transversal-and-if-a-80-find-the-values-of-and
