Answer:
cos (A+B+C)
Step-by-step explanation:
as A,B,C, are triangle we have A,B and C as 180
cost
3rd degree polynomial with 4 terms
Answer:
x-5=-3
Step-by-step explanation:
|x-5|+2=5
|x-5|=5-2
|x-5|=3
x-5=±3
so x-5=-3 is a correct step.
Answer:
x^ -10 or 1/x^10
Step-by-step explanation:
Answer:
x = 16
y = 16√3
Step-by-step explanation:
sin(30 degrees) = 1/2
x = 32/2 = 16
cos(30 degrees) = √3/2
y = 16√3
