Given that,
The area parameters are
A = 2.7 cm, B = 4.1 cm C = 4.5 cm
We want to find the angle extended by B.
Using cosine Rule
b² = a² + c² - 2ac•Cosθ
4.1² = 2.7² + 4.5² - 2 × 2.7 × 4.5• Cosθ
16.81 = 7.29 + 20.25 - 24.3•Cosθ
16.81 - 7.29 - 20.25 = -24.3•Cosθ
-10.73 = -24.3•Cosθ
Cosθ = -10.73 / -24.3
Cosθ = 0.4416
θ = Cos~1 (0.4416)
θ = 63.8°
The angle B is 63.8°
Simplified it is 4k = -14
X = -230/3 hope that helps
Answer:
A.
Step-by-step explanation:
It clearly states that the lines are parallel. If they don't intersect that would be the answer. If you put B. you would only be repeating the information that was already given
