You would then move the decimal how many places you were given
a. if the return trip is the same then the bird traveled 40miles
b. the time of the trip is x hours + 6/x-4
Hope this helps!
Since they are similar triangles, they are just enlarged versions of each other. This means that the left-most angle of triangle XYZ is also 35°.
Angles in a triangle add up to 180°, so we can find the missing angle by subtracting the two known angles from 180.
180 - 70 - 35 = 75
The right-most angle of triangle XYZ would be 75°.
Hope this helps!
It is a whole number, and is positive
