Answer:
the other person is wrong, its b, d, e, and f
Step-by-step explanation:
It's gonna be 5 - (2 + 4 -2)
according to order of operations, we have to solve inside the parentheses/brackets first (from left to right)
therefore, it will be
5 - (6 - 2)
=5 - (4)
Next, distribute the negative to the four and add normally.
= 5 - 4
= 1
Things to remember the sum of the measures of the interior and exterior angles at each vertex is 180 (supplementary angles)
add and equal to 180
3x-5+5x+17= 180
8x+12=180
8x= 168
x=21
substitute in the algebraic expression for exterior angle
3(21) -5=
63-5=58
58 degrees is the exterior angle
hope this helps
