Answer 5

do you agree that angle ADE is a right angle?

Answer 6

Yes

Answer 7

so ADE is 90 degrees

we see that a piece of ADE is 40 degrees. The other piece is x

so...

x+40 = 90

what must x be?

Answer 8

50

Answer 9

good

Answer 10

as for the angle with y in it, the 55 degree angle and the angle y add up to 180 degrees

because these two angles form a straight angle (which is 180 degrees)

so

55+y = 180

Answer 11

125

Answer 12

you are correct

Answer 13

Can you help with another?

Answer 14

sure

Answer 15

What are the values of x and y in the diagram?
A. x = 77°
y = 93
B. x = 87°
y = 83°
C. x = 77°
y = 83°
D. x = 87°
y = 93°

Answer 17

focus on the triangle

Rule: in any triangle, the 3 angles always add to 180 degrees

Answer 18

so

x+67+36 = 180
