Answer:
230 - 151 + 180 + (43 - 12) = 290
Step-by-step explanation:
Use PEMDAS.
Evaluate the expression in the parentheses:
230 - 151 + 180 + (43 - 12)
43 - 12 = 31
230 - 151 + 180 + 31
Add and Subtract From Left to Right:
79 + 180 + 31
259 + 31
290
<em>None of the given options are correct. </em>
d
all of the angles add up to equal 180 so we setup the equation as 45+3x=180
first you subtract each side by 45
135=3x
then you divide each side by 3 and get that
x=45
5 2/3
= (5 *3 + 2) / 3
= 17/3
