Question

Find x in the following figures :​

Answer 1

Answer:

x=30° this is the correct answer

Step-by-step explanation:

if AB and DC are parallel to each other

so this total value will be 120°

= x+3x=120°

= 4x=120°

x=120°/4

x=30°

⠀⠀⠀

Given

⠀⠀⠀

• AB || CD

⠀⠀⠀

To Find

⠀⠀⠀

• Value of x

⠀⠀⠀

Concept Used

⠀⠀⠀

✭ Co- Interior Angle

⠀⠀⠀

If the two lines are parallel, then co-interior angles add to give 180° and so are supplementary.

⠀⠀⠀

Solution

⠀⠀⠀

➞∠BAC + ∠DCA = 180° [ Co-interior Angle ]

⠀⠀⠀

➞ x + 3x = 180°

⠀⠀⠀

➞ 4x = 180°

⠀⠀⠀

➞ x = 180/ 4

⠀⠀⠀

➞ x = 45°

⠀⠀⠀

Hence, value of x is 45°.
