Question

FIND x IN THE FIGURE GIVEN ALONGSIDE:-

Answer 1

Answer:

x =115

Step-by-step explanation:

let's assume the two equal angles as 'y'

then 70 +2y = 180                 because they lie on a straight line

2y=180-70

2y=110

y=110/2

y=55

we also know that the sum of all angles in a quadrilateral = 360

the line the bisects angle 2y is perpendicular to the bottom line, where it is forming a 90 degree angle. so the angle lying beside the 90 degree angle is also 90 degree.                              lying on a straight line

hence y+100+x+90=360                    where y=55

55+100+x+90=360

245+x=360

x=115
