.
Now in your case
and
.
This shows that the only correct choice is A.
Answer:
1/4
Step-by-step explanation
you divide 25 divided by 25 the also divide 100 divided by 25 and u get 1/4
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.
