Answer:
z+42+42=180
Step-by-step explanation:
Since it is an isosceles triangle, the two base angles are the same and remember all the angles add to 180. So use this equation:
If you need to find z, it is 96.
Check: 96+42+42=180
y = -4x + 28
yeah-ya........ right?
It depends on what x is. For example, if x=4 then the difference between 15 and x would be 11.
Hope this helps!
