Answer 1

Step-by-step explanation:

a) Sum of interior angles = 180°

( interior angles are angles on the interior of a plane figure)

So The interior angles here are = 50°,100° and 30°

So the sum of 50°,100° and 30° are = 180°

e) The next one is the same but this time there is a right angle

And right angles are equal to 90°

So the sum of the interior angles will be=

70°+20°+90°

which will give us 180°

NB: When two straight lines intersect each other at 90˚ or are perpendicular to each other at the intersection, they form the right angle. A right angle is represented by the symbol ∟( Jux to help you further)
