Answer:
1. 15.49 cm
2. 14.39 cm
3. 17.32 cm
4. 11.53 cm
5. 5 cm
Step-by-step explanation:
In the given problem, you can solve the unknown side of the triangle using either Pythagorean Theorem or SOA CAH TOA method. In Trigo, you can use the Pythagorean Theorem if the triangle has 90 degrees, or it is a right triangle.
In the given problem, the angle of the triangles are unknown, therefore to solve the unknown side of triangles, we will you use the SOA CAH TOA.
In this case, since the given side are b and c, we can use CAH (Cos Teta equals Adjacent over Hypotenuse), and TOA ( Tan Teta equals Opposite over Adjacent)
Lets provide the solution for the number, and the rest have the same solutions and process.
b= 17, c= 3, let u is the angle
Cosu= 17/23, to get the angle, use inverse cosine.
The result will be 42.34°, and to get the unknown side, use TOA
Tanu=a/17, a=17Tanu
It will give you 15.49 cm
In the number 2 and 5, it will be the same when you rotate the triangle.
