Answer 1

So to do this you need a protactor and measure it with it, then add the total

Step-by-step explanation:

Answer 2

x=36
Step-by-step explanation:
for finding the total angles in a shape you have to follow the formula
(n-2)180
which n is the number of sides
so for a pentagon you will get
3.180=540 and by dividing it into the amount of angles you will get each angle's amount
so
540/5=108 -> each angle
back to the quastion you see the angle C is 108 and we have a triangle
and angles D and B are equal so by subtracting 108 from 180 (total angles in a triangle) we get 72 which is equal to both B and D angles so by dividing it to 2 you will get 36 which is the answer
