Question

pls help me in this question this is of line and angles
​

Answer 1

Answer:

Step-by-step explanation:

Sum of the angles = 180 deg.

5x - 60 +2x +20 = 180

7x -40 = 180

7x = 220

x = 220/7

x= 31 deg approximately

Answer 2

Answer: 31°

Step-by-step explanation:

❍ Given :-

• ∠1 = 5x - 60
• ∠2 = 2x + 20

❍ To Find :-

• Value of x

❍ Solution :-

We know that,

A straight is always equal to 180°.

So,

$\sf →5x - 60° + 2x + 20° = 180°$

$\sf →7x - 40° = 180°$

$\sf →7x = 180° + 40°$

$\sf →7x = 220°$

$\sf →x = \dfrac{220°}{7}$

$\sf →x = 31.42$ or approx 31°

Hence, x is equal to 31°.
