Question

7. In Fig. 7.20, find angleYED.​

Answer 1

Answer:

Angle YED = 135•

Step-by-step explanation:

Because

Angle EDZ = 45•

Angle EZD = 90•

So, Angle DEZ = 180• - (45• + 90•) = 45•

And as you can see

Angle DEZ + Angle YED = 180•(Linear equation)

So, Angle YED = 180• - 45• = 135• .

Answer 2

Answer:

137 degree

Step-by-step explanation:

angle XYZ+angle ZXY+angle YZX : 180 degree ( sum of interior angles of triangle)

32+60+x:180

x:88

angle YZX : 88

NOW angle yzx+angle yzd : 180 ( linear pair)

88+y:180

y:92

angle yzd : 92

Now angle yzd+angle ZDE :Angle YED(exterior angle property)

92+45:angle yed

137: angle yed
