Question

Solve for x helpppppp

Answer 1

x=30°

Explanation:

Find angles of the triangles:

Angles on a straight line:

180°-120°=60°

Opposite angles(intersection property):

55°= 55°

Sum of angles in a triangle = 180°

So:

------>60°+55°+2x+5=180°

------>120°+2x=180°

------>2x=180°-120°

------>2x=60°

------>x=60/2°

------>x=30°

Answer 2

let an agle be 'a' and 'b' ,

120°+a=180° ( linear pair )

a=120°-180°

a=60°

b=55°(opposite angle )

a+b+2x+5=180°(angle sum property)

60°+55°+2x+5=180°

120°+2x=180°

2x=180-120

2x=60

x=60/2

x=30

hence, the value of x is 30
