Don’t let the $$ 29 ^{circ }$$ angle fool you.. Remember: you can only use an angle when you are trying to solve for the 3rd side of a triangle! The $$ 29^ circ $$ does nothing for the law of cosines. (As an aside, you could use that angle with the law of sines .)You can even cross it out, if you want. Step 1

Law of Sines. Just look at it.You can always immediately look at a triangle and tell whether or not you can use the Law of Sines. You need either 2 sides and the non-included angle or, in this case, 2 angles and the non-included side.. The law of sines is all about opposite pairs.. In this case, we have a side of length 11 opposite a known angle of $$ 29^{circ} $$ (first opposite pair) and we
Law of Sines The law of sines is used to find angles of a general triangle. If two sides and the enclosed angle are known, it can be used in conjunction with the law of cosines …
The Law of Sines One method for solving for a missing length or angle of a triangle is by using the law of sines. The law of sines, unlike the law of cosines, uses proportions to solve for missing lengths. The ratio of the sine of an angle to the side opposite it is equal for all three angles of a triangle. The law of sines works for any triangle, not just right triangles.

In trigonometry, the law of cosines (also known as the cosine formula, cosine rule, or al-Kashi’s theorem) relates the lengths of the sides of a triangle to the cosine of one of its angles.Using notation as in Fig. 1, the law of cosines states = + − , where γ denotes the angle contained between sides of lengths a and b and opposite the side of length c.
It’s all about opposites: To use the law of sines, you need to know one opposite angle/side pair measurements. Cases when you can not use the Law of Sines. The picture below illustrates a case not suited for the law of sines. Since we do not know an opposite side and angle, we cannot employ the formula.

The Law of Cosines tells us that a squared is going to be equal b squared plus c squared. Now, if we were dealing with a pure right triangle, if this was 90 degrees, then a would be the hypotenuse, and we would be done, this would be the Pythagorean Theorem. But the Law of Cosines gives us an adjustment to the Pythagorean Theorem, so that we can do this for any arbitrary angle. So Law of
