<u><em>Answer:</em></u>
1. 15.49 cm
2. 14.39 cm
3. 17.32 cm
4. 11.53 cm
5. 5 cm
<u><em>Step-by-step explanation:</em></u>
In the given problem, you can solve the unknown side of the triangle using either<em> Pythagorean Theorem</em> or<em> SOA CAH TOA</em> method.<em> </em><em>In Trigo, you can use the Pythagorean Theorem if the triangle has 90 degrees, or it is a right triangle.</em>
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.
<u><em>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)</em></u>
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.
