Question

Can someone show me the steps for solving. I had help but I'm confused.

Answer 1

The sum of angles in any triangle is 180° So the missing angle in the bottom triangle is:

180-76-54=50°

Now that right angle (the square) is bisected by this 50° so the bottom angle of the inverted upper triangle is 90-50=40°

And again, because the sum of angles in a triangle is always 180°. The missing angle in the inverted triangle the "?" is:

180-70-40=70°

So "?"=70°

Answer 2

If i'm not mistaking, the value of the missing angle should be 65 degrees and i got this by subtracting 70 and 45 from 180 (180 is the total value of angles in a triangle) and i got 45 by dividing the right angle into 2. So we have 180-45-70= 65.
I hope it helps
