Determine leg of triangle
WebSolution: We know that the sum of the angles of a triangle adds up to 180°. Therefore, the unknown angle can be calculated using the formula. Sum of interior angles of a triangle = Angle 1 + Angle 2 + Angle 3. ⇒ 180° = 45° + 63° + Angle 3. ⇒ Angle 3 = 180° - (45° + 63°) Angle 3 ⇒ 72°. ∴ The third angle is 72°. WebFeb 2, 2024 · To calculate the isosceles triangle area, you can use many different formulas. The most popular ones are the equations: Given leg a and base b: area = (1/4) × b × √ ( 4 × a² - b² ) Given h height from apex …
