Step-by-step explanation:
For a given scale factor k
If k > 1 then expansion
If k < - 1 then expansion in the opposite direction
If 0 < k < 1 or - 1 < k < 0 then contraction
k = - 2 ← expansion in opposite direction
k = 1.5 ← expansion
k = ← contraction
k = - ← contraction
Answer:
4. Z ≈ 46.1°
5. T ≈ 45.2°
6. F ≈ 15.0°
Step-by-step explanation:
4.
We need to use the Law of Sines, which states that for a triangle with legnths a, b, and c and angles A, B, and C:
Here, we can say that ZY = a = 30, X = A = 110, XY = b = 23, and Z = B. Plug these in to find Z:
Solve for Z:
Z ≈ 46.1°
5.
Use the Law of Sines as above.
Solve for T:
T ≈ 45.2°
6.
Again, use the Law of Sines as before.
Solve for F:
F ≈ 15.0°
