Question

find x and please answer​

Answer 1

Answer:

Let the angle opposite to angle 72° be y

y + 72°= 180°

y= 180°- 72°

y = 108

4x + 6x + 108° = 180° by angle sum property of the triangle.

4x + 6x + 108° = 180°

10x + 108° = 180°

10x = 180°-108°

10x = 72°

x= 72/10

x= 7.2

Answer 2

Answer:

x =7.2

Step-by-step explanation:

let angle A be 4x

angle B be 6x

angle C be (180-72) - supplimentary angle

= 108

the value of x will be ,

4x +6x +108 = 180

10x = 180-108

x = 72/10

x = 7.2
