Question

. In the given figure AB II CD. Therefore the value of y is

Answer 1

Step By Step Explanation:

Angle Sum Property

Angle Sum Property • y + 2y + y = 180°

Angle Sum Property • y + 2y + y = 180°2y + 2y = 180°

Angle Sum Property • y + 2y + y = 180°2y + 2y = 180° 4y = 180°

Angle Sum Property • y + 2y + y = 180°2y + 2y = 180° 4y = 180° y = 45°

now putting the Value of y in the 3 angles:-

~ 2y = 2 × 45 = 90°

y = 45°

y = 45°

we will draw a line parallel to AB and CD on the base BD , i.e. , EF

so now we can find the angle D because it is exterior angle

y + 5y = 180°

6y = 180°

y = 30°
