Answer:
π/4
Step-by-step explanation:
The reference angle will be the minimum of the absolute value of the angle, and the difference of that absolute value and pi.
ref angle = min(|-3π/4|, π -|-3π/4|) = min(3π/4, π/4)
ref angle = π/4
Many types it just depends on what kind of element for example a chemical element is a certain type of atom
Answer:
Sorry it's acually (h+3)(h-9)
Defining variables
let n1 be the first number
n2 be the 2nd number
add them together, you get 218
n1+n2 =218
n1 is 47 less than n2
n1=n2-47
do some substitution
n2-47 +n2 = 218
solve for n2
then use n2 to figure out n1
