Answer:
let opposite side of 80° be y
80°+y = 180(linear pair)
y= 180-80
=100
30°+100°+x= 180°(angle sum property of triangle)
130° + x = 180°
x= 180-130
= 50°
hope you got your answer
50
Step-by-step explanation:
The sum of all angle in a triangle is 180°
by formula (n-2)×180,where n is no. of sides.
If you know a line makes 180° on both sides of itself.
The upper side of the triangle have total 80° Covered so
remaining is 100° Which is inside the triangle.
Now, You have 2 angles already if u reduce both of them from 180 You get a remaining of 50°, which is x
