Question

Question 6 and seven with explanation????

Answer 1

Answer:

6) Adjacent angles are two angles that have a common vertex and a common side but do not overlap. In the figure, ∠1 and ∠2 are adjacent angles. They share the same vertex and the same common side.

7) there is a property of triangles stating "exterior angle of a triangle = sum of its opposite interior angles"

60° + a = 135°

a = 135° - 60°

a = 75°

pls mark me as the brainliest

Answer 2

6]they are adjacent angles

7]first 180-135=45

after angle sum property

63+45+a=180

180-108=72
