Answer:
x = 60
y = 50
Explanation:
in a triangle, the sum of all its angles should be 180°. so, to find x, we can subtract the known values from 180° like this:
180° - 50° - 70° = 60°
thus, x is 60.
using the same method, we can find the remaining angle of the other triangle:
180° - 50° - 60° = 70°
now, we know the values of x and the angle next to it. on a straight line, the sum of angles also adds up to 180°. therefore:
180° - 60° - 70° = 50°
i hope this helps! :D
