Question

angles of quadrilateral are 85° ,95° ,x° ,(X +10)° . find the x​

Answer 1

Answer:

85+95+x+(x+10) =360 {angle some property}

85+95+10+x+x=360

190+2x=360

2x=360-190

x=170/2

x=85

therefore the value of x=85

hope this will help you

Answer 2

Answer:

x = 85

Step-by-step explanation:

The total sum of all angles of a quadrilateral is 360 *degree*

Therefore,

85 + 95 + x + ( x + 10 ) = 360

85 + 95 + x + x + 10 = 360 [opening the brackets]

190 + 2x = 360

2x = 360 - 190

2x = 170

x = 170/2

x = 85
