Answer:
tan θ = 
Step-by-step explanation:
We are given that cot θ = 1.5 and cotangent is the cofunction of tangent.
cot θ = 
tan θ = 
We can find the answer to tan θ by taking the reciprocal of the answer to cot θ.
cot θ = 1.5
Then, tan θ =
X= 9th student test score
Add the 9 test scores and divide that total by 9 to equal the average.
(56 + 92 + 78 + 64 + 85 + 83 + 91 + 77 + x)/9= 78
add in parentheses
(626 + x)/9= 78
multiply both sides by 9
626 + x= 702
subtract 626 from both sides
x= 76
ANSWER: 76 is the score needed by the 9th student for a mean of 78.
Hope this helps! :)
