Right Triangle Formula
a2 + b2 = c2Take the square root of both sides
c = √a2 + b2c = √702 + 502
c = √4900 + 2500
c = √7400
c = 86.023252670426
Calculate Angle A:
| sin(A) = | OPPOSITE |
| HYPOTENUSE |
| sin(A) = | a |
| c |
| sin(A) = | 70 |
| 86.023252670426 |
Sin(A) = 0.81373347120673
Angle A = 54.4623°
Calculate Angle B:
| sin(B) = | OPPOSITE |
| HYPOTENUSE |
| sin(B) = | b |
| c |
| sin(B) = | 50 |
| 86.023252670426 |
Sin(B) = 0.5812381937191
Angle B = 35.5377°
Calculate inradius:
| inradius = | ab |
| a + b + c |
| inradius = | (70)(50) |
| 70 + 50 + 86.023252670426 |
| inradius = | 3500 |
| 206.02325267043 |
inradius = 16.988373664787
Angle A = 54.4623
Angle B = 35.5377
Side A = 70
Side B = 50
Side C = 86.023252670426
Angle B = 35.5377
Side A = 70
Side B = 50
Side C = 86.023252670426

What 1 formula is used for the Right Triangles Calculator?
What 8 concepts are covered in the Right Triangles Calculator?
- cos
- cos(θ) is the ratio of the adjacent side of angle θ to the hypotenuse
- inradius
- a radius of an inscribed circle or sphere
- pythagorean theorem
- a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides
a2 + b2 = c2 - ratio
- indicates how many times one number contains another
- right triangles
- sin
- sin(θ) is the ratio of the opposite side of angle θ to the hypotenuse
- tangent
- the straight line that just touches the curve at that point
- triangle
- a flat geometric figure that has three sides and three angles
