Question

If you are given the length of one side of a right triangle and also are given the measure of one additional angle besides the right angle, what method should you use to solve the right triangle?



Use Pythagorean theorem to find sides, then trigonometric ratios to find angles.


Use trigonometric ratios to find a side, then use Pythagorean theorem to find the other side, then use sum of angles of a triangle add up to 180 to find the missing angle measure.


Use Pythagorean theorem to find the remaining angle measure, then use triangle inequality to find the remaining sides.


Use trig ratios to find the remaining angle, then use Pythagorean theorem to find the remaining side.

Answer 1

i think option 2 or 4 >.< I would double check though

Answer 2

Answer 3

To SOLVE A TRIANGLE means to know all three sides and all three angles. When we know the ratios of the sides, we use the method of similar figures. That is the method to use when solving an isosceles right triangle or a 30°-60°-90° triangle. When we do not know the ratio numbers, then we must use the Table of ratios. The following example illustrates how.
The general method
Example 1. Given an acute angle and one side. Solve the right triangle ABC if angle A is 36°, and side c is 10 cm.
Angle A = 36 degrees
Solution. Since angle A is 36°, then angle B is 90° − 36° = 54°.
To find an unknown side, say a, proceed as follows:
1. Make the unknown side the numerator of a fraction, and make the known side the denominator.
Unknown
Known = a
10
2. Name that function of the angle.
Unknown
Known = a
10 = sin 36°

3. Use the trigonometric Table to evaluate that function.
Unknown
Known = a
10 = sin 36° = .588
4. Solve for the unknown side.
a = 10 × .588 cm = 5.88 cm


I hope this helped :)
