Answer:
60.65
Step-by-step explanation:
The Law of Cosines can help you figure this out. Call the given sides "a" and "b" and the given angle "C". Then the third side, "c" will satisfy the relation ...
c² = a² + b² -2ab·cos(C)
= 33² +37² -2·33·37·cos(120°) = 3679
c = √3679 ≈ 60.65476 ≈ 60.65
The length of the third side is about 60.65 units.
Answer:
(D) Divide the first equation, , by 2.
Step-by-step explanation:
Given:
We need to find the operation performed on equation so as to get resultant equation as:
From Above we can see that there is no change in equation 2 with respect to resultant equation.
Also Resultant equation is simplified form of equation 1.
Simplifying equation 1 we get;
We can see that 2 is the common multiple on both side.
Hence we will divide equation 1 with 2 we get
which is the resultant equation.
Hence (D) Divide the first equation, , by 2 is the correct option.
