WebStep 1: Calculate “s” which is the semi-perimeter of a triangle i.e, perimeter divided by 2 $$s = { {a + b + c} \over 2}$$ where a, b, and c are the sides of the triangle. Step 2: Then calculate the area using the formula provided … WebThe 45°-45°-90° triangle, also referred to as an isosceles right triangle, since it has two sides of equal lengths, is a right triangle in which the sides corresponding to the angles, 45°-45°-90°, follow a ratio of 1:1:√ 2. Like the 30°-60°-90° triangle, knowing one side length allows you to determine the lengths of the other sides ... WebSep 8, 2024 · In this triangle we only know two sides ( a =4 cm y c =6 cm) and the angle they form (B=85°). First we have to find the length of side b. For this we use the Law of Cosines: So, we get the side b =6.92 cm. … gymnosperm literally means
