A theorem is a notion that has been continuously proven through logic and mathematics. These notions are accepted to be true based on the given arguments. Many mathematicians have developed many theorems in the past already. The answer to this problem is <span>B. A conclusion proved by deductive reasoning</span>
The question is not clear. As much as i understand it:
3x-12=21
3x=21+12
3x=33
x=11
4x=s
(plug in the value of x, as found in the previous step)
4(11)=s
44=s
hope i helped.
Answer:
42° and 138°.
Step-by-step explanation:
Here we use the identity that
.
Now, to find
, we make use of the inverse sine function:
![x = sin^{-1}(0.0091)](https://tex.z-dn.net/?f=x%20%3D%20sin%5E%7B-1%7D%280.0091%29)
![\boxed{ x = 42^o.}](https://tex.z-dn.net/?f=%5Cboxed%7B%20x%20%3D%2042%5Eo.%7D)
Another solution to this is
Thus, the values of
in the interval
for which
are 42° and 138°.
We have that
cos A=0.25
so
A=arc cos (0.25)-------> using a calculator----> A=75.5225°
Round to the nearest hundredth-----> A=75.52²
the answer is
the option <span>75.52°</span>
Answer:
-7k+21
Step-by-step explanation:
<em>Distributive Property:</em>
