Answer:
Step-by-step explanation:
a) tanθ = x/3
θ = arctan(x/3)
:::::
b) cosθ = 9/x
θ = arccos(9/x)
Because completementary angles add up to 180 degrees (angle 3 and angle 4)
and interior angles of a triangle will also add up to 180 degrees
if you compare these two facts, then angle 4 equals the 2 non adjacent interior angles

Answer:
I think its (6,-3)
Step-by-step explanation:
Answer:
distance is 6.4 units
Step-by-step explanation:
use a^2+b^2=c^2 to find the hypotenuse which is the distancr
you can count the sides base is 4 and height is 5 Square the numbers
16+25= c^2
41=c^2
find the square root of 41 to get rid of the squared
which is 6.40 so 6.40= c and c is the distance
