WebTo find the third side of a triangle first we need the perimeter of the triangle. Perimeter of triangle means the sum of all 3 sides which is given in this q... Webuse The Law of Cosines to calculate the unknown side, then use The Law of Sines to find the smaller of the other two angles, and then use the three angles add to 180° to find the last angle. Example 1 In this triangle we know: angle A = 49° b = 5 and c = 7 To solve the triangle we need to find side a and angles B and C.

WebFeb 24, 2024 · 6. Add up the lengths of the three side lengths to find the perimeter. Recall that the perimeter P = a + b + c. Now that you know the lengths of sides a, b and c, you simply need to add the lengths together to find the perimeter. In our first example, P = 3 + 4 + 5, or 12. In our second example, P = 6 + 8 + 10, or 24 . WebJul 19, 2024 · Triangle Third Side computes the third side (c) from two sides (a &b) and adjacent angle (A).
