pi·18.6^2·123°/360° - 1/2·18.6^2·SIN(123°) = 226.3
Answer:
d:192
Step-by-step explanation:
Answer: a the first answer is right
The value would be 4.
First, you have to do 4 + 3 because it's in parenteces. This equals 7
Secondly, you have to do 2 x 7, which is 14.
Last you have to do 18 - 14 which is 4.
Sin230=sin(180+50)=sin180cos50+cos180sin50=-sin50 answer 1
