The Cosine Law:
c² = a² + b² - 2 a b cos C
14² = 28² + b² - 56 · b · √3/2
196 = 784 + b² - 28√3 b
b² - 28√3 b + 588 = 0
b 1/2 = (28√3 +/- √(2352 - 2352 )) / 2 = 28√3 / 2 = 14√3
Answer:
The given measurements determine one triangle.
Answer:
The measure of .
Step-by-step explanation:
Given,
AB║CD and
m∠2 = 60°
Solution,
Since, in the figure given in attachment line segment AB is parallel to line segment CD. And t is the transversal line.
The theorem of parallel lines states that,
"If two lines are parallel and cut by a transversal line then the pair of corresponding angles are congruent."
So according to the theorem of parallel lines,∠2 and ∠6 makes a pair of corresponding angle.
And the measure of corresponding angle is equal.
So, m∠2 = m∠6
Thus the measure of .
