Question

twice of x is 30 less than y then the value of x and y​

Answer 1

Answer:

hope it help u

Step-by-step explanation:

According to question

2 x = y - 30°

⇒ y = 2x + 30° …… (i)

Also, we know that

sum of x + y = 180° …… (ii)

Tip:- Sum of supplementary angles = 180°

Straight lines measure 180°. That means that these two angles are supplementary.

Complementary angles form a right angle (L shape) and have a sum of 90°. Supplementary angles form a straight line and have a sum of 180°.

Now, putting the value of y in eq (ii), we get

⇒ x + 2x + 30° = 180

⇒ 3 x = 180° – 30°

⇒ x = 50°

And y = 2x + 30°

⇒ y = 2(50°) + 30°

⇒ y = 100° + 30°

⇒ y = 130°
