Расчет прямоугольного треугольника с катетом a=2 и углом β°=20

Калькулятор прямоугольного треугольника — это инструмент, который помогает вычислять различные параметры прямоугольного треугольника, такие как длина сторон, площадь, периметр,углы и высоты.

c = \(\frac{a}{\cos{β°}}\) = \(\frac{2}{\cos{(20°})}\) = \(\mathtt{\text{2.13}}\)

α° = \(90°-β°\) = \(90°-20°\) = \(\mathtt{\text{70}}°\)

h = \(a·\sin{β°}\) = \(2·\sin{(20°)}\) = \(\mathtt{\text{0.684}}\)

b = \(\sqrt{c^2 - a^2}\) = \(\sqrt{\mathtt{\text{2.13}}^2-2^2}\) = \(\sqrt{4.5369-4}\) = \(\sqrt{0.536899999999999}\) = \(\mathtt{\text{0.733}}\)b = \(h·\frac{c}{a}\) = \(\mathtt{\text{0.684}}·\frac{\mathtt{\text{2.13}}}{2}\) = \(\mathtt{\text{0.728}}\)b = \(c·\cos{α°}\) = \(\mathtt{\text{2.13}}·\cos{(70°)}\) = \(\mathtt{\text{0.729}}\)b = \(c·\sin{β°}\) = \(\mathtt{\text{2.13}}·\sin{(20°)}\) = \(\mathtt{\text{0.729}}\)b = \(\frac{h}{sin{α°}}\) = \(\frac{\mathtt{\text{0.684}}}{sin{(70°)}}\) = \(\mathtt{\text{0.728}}\)b = \(\frac{h}{sin{β°}}\) = \(\frac{\mathtt{\text{0.684}}}{sin{(20°)}}\) = \(\mathtt{\text{0.728}}\)b = \(\sqrt{\frac{c^2 - \sqrt{c^4-4·c^2·h^2}}{2}}\) = \(\sqrt{\frac{\mathtt{\text{2.13}}^2 - \sqrt{\mathtt{\text{2.13}}^4-4·\mathtt{\text{2.13}}^2·\mathtt{\text{0.684}}^2}}{2}}\) = \(\sqrt{\frac{4.5369-\sqrt{12.0929980644}}{2}}\) = \(\sqrt{0.53}\) = \(\mathtt{\text{0.728}}\)

S = \(\frac{hc}{2}\) = \(\frac{\mathtt{\text{0.684}}·\mathtt{\text{2.13}}}{2}\) = \(\mathtt{\text{0.728}}\)

---

R = \(\frac{c}{2}\) = \(\frac{\mathtt{\text{2.13}}}{2}\) = \(\mathtt{\text{1.06}}\)

---

mc = \(\frac{c}{2}\) = \(\frac{\mathtt{\text{2.13}}}{2}\) = \(\mathtt{\text{1.06}}\)

---

r = \(\frac{a+b-c}{2}\) = \(\frac{2+\mathtt{\text{0.728}}-\mathtt{\text{2.13}}}{2}\) = \(\mathtt{\text{0.299}}\)

---

P = \(a+b+c\) = \(2+\mathtt{\text{0.728}}+\mathtt{\text{2.13}}\) = \(\mathtt{\text{4.86}}\)
