Answer:
x=30°
Step-by-step explanation:
To find the value of x we need atleast 2 other angles, and we do we have one 70, but we need to get another angle from the info given outside the triangle,
Notice, the angle beside 100 can be found by simply subtracting 180-100
(since angles are on a straight line [Supplementary angles]
So, the angle is 80
Now, we know that the angles inside a triangle add up to 180
So basically, to find x:
70+80+x = 180
150+x = 180
x = 180-150
x=30°
Hoep this helps!
