Answer:
Rhion did better in maths test.
Step-by-step explanation:
Given that:
Rhion scored 14 out of 17.
We will find percentage and then compare them.
Percentage = 
Percentage = 
Percentage = 82.35%
Rhion scored 31 out of 39.
Percentage = 
Percentage = 79.48
On comparing,
82.35 > 79.48
Hence,
Rhion did better in maths test.
Answer:
45.7
Step-by-step explanation:
Hello there!
We can calculate the missing angle using trigonometry
here are the trigonometric ratios
sin = opposite over hypotenuse
cos = adjacent over hypotenuse
tan = opposite over adjacent
We are given x's opposite side length (8) and x's adjacent side length (7.8)
we are given the information to use the trigonometric ratio tangent
so now we create an equation (remember tan - opposite over tangent)

now we solve for x

we're left with

finally we want to get rid of the tan
To do so we take the inverse of tan (arctan^-1) and apply it to each side

so x = 45.7252243
finally we round to the nearest tenth and get that the answer is
45.7
