WebFeb 2, 2024 · In such a triangle, the legs are equal in length (as a hypotenuse always must be the longest of the right triangle sides): a=b a = b. One leg is a base, and the other is the height – there is a right angle between them. So the area of an isosceles right triangle is: \text {area}=\frac {a^2} {2} area = 2a2.

WebMay 9, 2024 · To check the solution, subtract both angles, 131.7° and 85°, from 180°. This gives α = 180 ∘ − 85 ∘ − 131.7 ∘ ≈ − 36.7 ∘ which is impossible, and so β ≈ 48.3°. To find the remaining missing values, we calculate α = 180° − 85° − 48.3° ≈ 46.7° . Now, only side a is needed. Use the Law of Sines to solve for a by one of the proportions.
