Question

find x.please tell the answer.​

Answer 1

Answer:

if produced angle =72 then in a triangle produced angle =sum of opp. interior angle then 6x+4x=10x then x=7.2

Answer 2

Step-by-step explanation:

Let the third Angle of the triangle be a.

Therefore,

Angle a + 72° = 180° --(Linear Pair Angles)

Angle a = (180 - 72)°

Therefore,

Angle a = 108°

Thus,

Third Angle of the triangle is 108°.

We know that,

Sum of all Angle of a triangle is 180°

Therefore,

4x + 6x + 108° = 180°

10x = 180 - 108

x = (72/10)°

Therefore,

x = 7.2°
