Sorry i don’t know the answer but i’m new to this app, and was wondering what brainliest is?:)
D.) because it's proportional. Y=x/2
the answer is in the picture above
X would equal 70°.
For every triangle, all interior angles add up to 180°. This means that we can add together 42 and 68 to get 110°. Because the sum of all interior angles in a triangle must be 180°, we subtract 110 from 180 to see how much more we need, which gets us 70°.
I hope this helps!
