Step-by-step explanation:
Answer:
A. -68
B. 37
C. -61
D. 171
Step-by-step explanation:
Rule for A, B, D: 2 negatives is the same as addition
(how I did C: add them together then add the negative)
The angles opposite equal sides are also equal. The sum of angles in a triangle is 180. So 2x + 27 + 2x + 27 + 3x + 28 = 180.
7x + 82 = 180
7x = 98
x = 14
Now plug x into each angle to find their measures.
I believe that answer is 31
