It could not be 73º because if you add that to 120 then it will be more than 180 degrees, which is the total number of degrees in a triangle. Hope this helps!
Answer:
Either y =
or, y =
Step-by-step explanation:
We have to solve the following quadratic equation
45y² + 15y - 10 =0
Now, dividing both sides with 5 we get, 9y² + 3y -2 =0
Hence, to solve the above equation we have to factorize the left-hand part of the equation.
So, 9y² + 3y - 2 =0
⇒ 9y² +6y -3y -2 =0
⇒ (3y +2) (3y -1 ) =0
⇒ Either (3y +2) =0 or (3y -1) =0
⇒ Either y = or, y = (Answer)
Answer:
32.6
Step-by-step explanation:
opp/adj = 3.2/5
I= tan -1(3.2/5)
I =32.6192
=32.6

Answer:
irrational number, non-repeating decimal
Step-by-step explanation:
√18 = √9·√2 = 3·√2.
√2 is an irrational, non-repeating decimal (my calculator shows it to be approx. 1.414213562..... )
and so √18 is the same.
