Question

If ( 4x+35°) and ( 3x - 15°) form a straight line, then find the value of x. What special name given to these types of angles?

Give step-by-step explanation.​

Answer 1

Answer:

4x + 35° + 3x - 15° = 180° ( straight line )

7x + 20° = 180°

7x = 180° - 20°

7x = 160°

x = 160° / 7

Answer 2

Answer:

we know that,

sum of of linear pair is equal to 180 degree

( 4x+35°) + ( 3x - 15°)=180°

7x+20°=180°

7x = 180° - 20°

7x = 160°

x. = 160°/7

this type of angle is called linear pair
