Question

find the value of X from the given figure​

Answer 1

Answer:

x = 100°

Explanation:

As we know that exterior angle of a triangle is equal to the sum of it's opposite interior angles..

Therefore , BAC + ABC = 110° ---(1)

BAC =

Also , BAC + 150°. = 180° (L.P)

BAC = 180° - 150°

BAC =. 30°

putting the value of BAC in equation no. 1

30° + ABC = 110°

ABC = 110° - 30°

ABC = 80° ..

Now ; ABC + x = 180° (L .P)

80° + x = 180°

x = 100° ...
