The value of x would equal 55
Answer:
The answer is "Option a"
Step-by-step explanation:
The Rejecting or the null hypothesis is refused by the refuting were used when the significance for our data analysis is less than the cut-off points, for example, either 0.05 or 0.01, therefore reject the null accept the alternative hypothesis, that's why in this question, the first choice is correct.
Cos x = 1/√10
sin x = √( 1 - 1 /10 ) = √9/10 = - 3/√10 ( because x is in Q IV )
cot 2 x = cos 2 x/sin 2x = ( cos²x - sin²x)/ (2 sinx cosx ) =
= ( 1/10 - 3/10 )/(2 * (-3/√10)*1/√10)= (- 8/10 ) / (-6/10 ) = 8/6 = 4/3

Answer:
h=11.3 and c=8(or 8.1 depending on what you do first)
Step-by-step explanation:
so we do the same thing like last time and 8√2 rounded is 11.3, and 7/√3, or 7√3/3 is 4( 4.04 gets rounded down). now we multiply by two because of the theorems and get 8(if this is wrong then try 8.1 because the answer differs depending on what you do first.)
