S = (n-2) x 180 to find the total angles.
5-2*180
3*180
540
540-86-140-138-59=117
The answer is 15%.
Just divide 3 and 20.
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:
z+42+42=180
If you need to find z, it is 96.
Check: 96+42+42=180
Answer:the last one
Step-by-step explanation:
Divide 12 by 10.4
