Answer: $178.13
Step-by-step explanation:
418x0.16=66.88
22.25x5=111.25
111.25+66.88=178.13
A.
because the total distance of every triangle 180. Add the two other angles so 42+ 57 =99. Then you have to subtract those two combined angles to find the missing one from the total distance, which is 180. 180-99=81. the answer is A. 81
If I'm reading this right, than all 9 angles are acute?
The answer is 16 because you have to do the exponents, than the division, then the subtraction, and lastly, the addition.
