If I know the measures of all three angles and none of the sides of an oblique triangle, neither the Law of Sines nor the Law of Cosines can be used to find the length of a side.Group of answer choicesTrueFalse

Which of the following can be used to find the measure of an angle of a triangle when the lengths of the sides are known?*a. Law of Sinesb. Law of Cosinesc. Law of Inertiad. Law of Entropy

In order to apply the law of cosines to find the length of the side of a triangle, it is enough to know which of the following?A.The lengths of two of the triangle's sides and the measure of the angle between themB.The measure of an angle and the length of the side opposite that angleC.The area of the triangle

Solving a right triangle means finding the missing lengths of its sides and the measurements of its angles.Group of answer choicesTrueFalse

A surveyor needs to find the length from point A to point C across a lake as shown in the figure below. The measurements of which of the following angles and side lengths are sufficient for the surveyor to determine the length of 𝐴𝐶‾AC  using only the law of sines?(Note : The law of sines says 𝑎𝑠𝑖𝑛𝐴=𝑏𝑠𝑖𝑛𝐵=𝑐𝑠𝑖𝑛𝐶.sinAa​ = sinBb​ = sinCc​ .)

1. It is possible to solve a triangle if the only given information consists of the measures of the three angles of the triangle.. In general, it is not possible to use the 2 lengths of all the sides. Law of Sines to solve a triangle for which we are given the3. Given ∆ABC with A = 30°, c = 3 cm, and a = 2.5 cm. There can be more than one triangle with the given dimensions that can be drawn. 4. In a scalene triangle, the largest angle is always the opposite the longest side and the smallest angle is always the opposite teh shortest side.5. Given ∆ABC with a A = 57°, a = 15m, and c = 20 m. There is no triangle for these values
