Answer:
4, 5, 6
Step-by-step explanation:
An exterior angle is an angle outside of the triangle
The tangent of the angle is
... tan(α) = ay/ax = -8.6/6.1
Then the angle (measured CCW from +x) is
... α = arctan(-86/61) ≈ 305°
Answer:
D: 2f+15
Step-by-step explanation:
f is the number of stamps from France that Carlotta owns.
Twice this amount is 2f
Then, 15 more than twice this amount is 2f + 15, and this is the expression that represents the number of American stamps that Carlotta owns
