The Legal Angle: Do You Need An Attorney For A Car Accident You Didn’t Cause?

The Legal Angle: Do You Need An Attorney For A Car Accident You Didn’t Cause? – We cannot use the Pythagorean theorem. Why not? Later, area = ½ bh Large angles are horizontal to long sides and vice versa. The sum of the two smallest sides must be greater than the third. A B C a b c

4 There are three possible configurations that allow us to use the Law of Sines. They are presented below. Here you don’t have the opposite angle and the side, but you can easily find the angle opposite the wall you know, because the sum of the angles of a triangle must be 180°. ASA SAA You can have an angle, a side, then another angle You can have a side, then an angle, then another angle. This means you should already know the corner and the wall opposite it (and another side or). angle) using the law of sines. SSA You can have two sides and then an angle that is not between them.

In addition to the ASA triangle, you always have enough information for 1 whole fraction and the other half. Start here to find the fourth clue. Once you know the second angle, you can subtract from 180 to find the third angle. Use given rather than calculated data whenever possible to avoid rounding errors.

…you have 3 parts of a triangle and you have to find the other 3 parts. It can’t be just 3 dimensions or you won’t have enough information to solve the law of sines equation. Use the law of sines if given: AAS – 2 angles and 1 adjacent side ASA – 2 angles and their connecting side ASS – (SOMETIMES) 2 sides and their adjacent angle

Let’s draw a perpendicular line and call its length h. We do this to get a right triangle that we know how to work with.  c a h   b Let’s write some known trigonometric functions from right triangles. Solve these for h Since both = h, we can divide both sides by AC ac ac

If we draw a perpendicular line, h from C to AB, we can divide the triangle into two right triangles, ACD and BDC. C b a h a is the side opposite A and b is the side opposite B. A B D Let’s call h for the perpendicular height (not h for the hypotenuse). h b h a sin A = sin B = h = b sin A h = a sin B Then b sin A = a sin B

If we divide both sides of the equation by sin A and sin B: b sin B = a sin A If we draw a perpendicular from A to BC, we find: b sin C = c sin B Rearranging: b sin B = c sin C

You can use the first form of the formula to find the side lengths and the second form of the equation to find the angles. a sin A = b sin B c sin C sin A sin B sin C a = b c or

If we are given two angles of a triangle and the length of the side opposite one of the angles, we can use the law of sines to find the length of the side opposite the other angle. For example, find the length of side a a a 7 cm 118° 39° A B C Using the law of sines, a sin 118° = 7 sin 39° It is easiest to use the formula a/sin when trying to find the length of a side. A = b/sin B. Ask students to wait until the last step in the equation to evaluate the sines of the required angles. This avoids rounding errors. a = 7 sin 118° sin 39° a = (up to 2 d.b.)

Note that side lengths and corners are rounded. This means, for example, that the sum of the three angles of a triangle does not exactly equal 180°. State the angle and its opposite side. Open another angle and ask students to find the side opposite it using the sine rule. Create a new instance by changing the shape of the triangle.

If we are given the length of two sides of a triangle and the angle opposite one of the given sides, then we can use the law of sines to find the angle opposite the other given side. For example, find the angle B 6 cm 46° B 8 cm A C Using the law of sines, sin B 8 = 6 sin 46° When trying to find an angle, it is easiest to use the formula sin A/a =. sin B/b sin B = 8 sin 46° 6 sin–1 B = 8 sin 46° 6 B = 73.56° (up to 2 d.p.)
