So,
Answer:
2
Step-by-step explanation:
In this case, you have to substitute the w for -1, and then do the operation:
-6( -1 )^2 + 13( -1 ) + 21
-6( 1 ) - 13 +21
-6 -13 + 21
-19 + 21
2
you would use sine
sine = opposite side / hypotenuse
and solve for opposite side (x)
so sine of 70*14= which is about 13.146
