Answer:
-0.5 or -1/2 or A
Step-by-step explanation:
180 degrees is Pi radians. To find out what the measure is in the paranthesees, divide 180 by 6 and get 30. Now multiply it by 7 to get 210. The question is asking for the sin(210). The sin of 210 is -0.5
Answer:
x = 1/3 and y = 3
Step-by-step explanation:
It is given the system of equations
3x + 2y = 7 ----(1)
-3x + 3y = 8 ----(2)
<u>To find the solution</u>
Add eq(1) and eq (2) we get,
3x + 2y = 7 ----(1)
<u>-3x + 3y = 8</u> ----(2)
0 + 5y = 15
y = 15/5 = 3
Substitute the value of y in eq(1)
3x + 2y = 7 ----(1)
3x + 2*3 = 7
3x + 6 = 7
3x = 7 - 6 = 1
x = 1/3
Therefore
x = 1/3 and y = 3
