Question

Find the value of w. ​

Answer 1

180

Explanation:

if a is 160 round up and it 180 simple math

Answer 2

Let the midpoint of AB and CD be O as they intersect at a point. (Refer to image)

Step-1: Find ∠BOD.

• 168 + ∠BOD = 180
• => ∠BOD = 180 - 168
• => ∠BOD = 12°

Step-2: Find w.

• 12 + w + 90 = 180
• => 102 + w = 180
• => w = 180 - 102
• => w = 78°
