Question

Help please . Find x

Answer 1

It is 7 angles which means all the numbers added must =900 so by subtracting we will find our answer
900-(142+140+136+150+148+ a right angle symbol which means 90)=900-716=184

So the final answer is 184 degrees

Answer 2

134

Explanation:

If you know a triangle angles add up to 180 degrees, for every side after that is plus 180 degrees. For seven, it is 900 degrees. Add the values then subtract. You get 134.
