Step-by-step explanation:
Answer:
< BAF <DAF
Step-by-step explanation:
The first angle is < BAF
The second angle is <DAF
The ray A,F has to be in the name of the angle
Step-by-step explanation:
Use SOH-CAH-TOA.
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
Let's start with #12. The hypotenuse is 18. The side adjacent to ∠B is 6. Since we have the adjacent side and hypotenuse, we should use cosine.
cos B = 6/18
Solving for B:
B = cos⁻¹(6/18)
Using a calculator:
B ≈ 70.5°
Now let's do #14. The side adjacent to ∠B is 19, and the side opposite of ∠B is 22. Since we have the adjacent side and opposite side, we should use tangent.
tan B = 22/19
Solving for B:
B = tan⁻¹(22/19)
Using a calculator:
B ≈ 49.2°
Po ^2 = 6^2 + 8^2
Po^2 = 36 + 64 = 100
So Po = 10
Sin x = 8/po = 8/10= 0.8
Cos y = 6/po = 6/10=0.6
