Answer:
The order of operations is Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.
Step-by-step explanation:
The order of operations is PEMDAS.
P: Parenthesis
E: Exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction
An easy way to remember PEMDAS is, please excuse my dear aunt sally.
Hope this helps!
If not, I am sorry.
Answer:
C^2=A^2+B^2
=11.87^2+18^2
= 140.90+324
= 464.9
C= square root of 464.9
= 21.56, the hypotenuse
Siny= 18/21.56
= 0.835
y =Sin^-1(0.835)
=56.62
Sinx= 11.87/21.56
=0.551
x =Sin^-1(0.551)
= 33.44
thats one way, i chose a longer way cuz i think its better to go through the steps
Step-by-step explanation:
Sin=opp/hyp
Cos=adj/hyp
Tan=opp/adj
you can use these to solve it other ways
4x^2+3/2x-7
