A = B = C = = 11 Points] Find the agea of the triangle having the indicated angle and sides. (Round your answer to one decimal place.) Δ = 126∗,a = 91,c = 13.The reason is that using the cosine function eliminates any ambiguity: if the cosine is positive then the angle is acute, and if the cosine is negative then the angle is obtuse. This is in contrast to using the sine function; as we saw in Section 2.1, both an acute angle and its obtuse supplement have the same positive sine.Ask any math/science homework question and receive answers from other members of the community.

Best Answer. now side length formula is now initially a=3, …. The side lengths of any triangle are related by the Law of Cosines, the formula shown below. c^2 = a^2 + b^2 - 2ab cos theta Complete parts (a) and (b) below, a.Estimate the change in the side length c when a changes from 3.00 to 3.05, b changes from 2.00 to 1.94, and theta changes ...C. The equation relating the three sides of a triangle is. c 2 = a 2 + b 2 − 2 a b cos ( C) 🔗. You can see that when C is a right angle, , cos 90 ∘ = 0, so the equation reduces to the Pythagorean theorem. 🔗. We can write similar equations involving the angles or A or .This may be a bit more work than to calculate the resultant using the Law of Cosines and the Law of Sines as was done in the preceding section. However, if the two vectors 1 and 2 are already given in component form and if one wants the resultant in component form as well, as will often be the case, the calculation is simpler.The Law of Cosines is used to find the remaining parts of an oblique (non-right) triangle when either the lengths of two sides and the measure of the included angle is known (SAS) or the lengths of the three sides (SSS) are known. In either of these cases, it is impossible to use the Law of Sines because we cannot set up a solvable proportion.1513 Orders prepared.
