Answer:
yea
Step-by-step explanation:
Using the cosine rule, a² = b² + c² -2 bc cos θSImplifying the equation in terms of cos theta,
cos(θ) = (a² + c² - b²)/(2bc)
(a² + c² - b²)/(2bc) > 0 a² + c² - b² > 0
assuming b and c are non zeros, the resulting inequality should be
a² + c² > b²
THe appicable inequality is a
If we assume that the figure is a triangle with a supplementary angle outside the triangle ABD, ∠F. Given that angle D is 31 and angle A is 27. Therefore, angle B is 122. Then, angle F is supplementary to angle D, meaning angle F will have a measurement of 180 - 31 = 149.
