The difference between two right sides of a right triangle is 7cm, and the area is 30cm 2

The difference between two right sides of a right triangle is 7cm, and the area is 30cm 2

Let the shorter right angle side length be xcm, the longer one be (x + 7) cm, 12x · (x + 7) = 30, and the result is as follows: x2 + 7x-60 = 0, ∧ (x + 12) (X-5) = 0, ∧ x = 5 or x = - 12 (rounding off). 5 + 7 = 12cm, 52 + 122 = 13cm. The length of hypotenuse is 13cm

If the sum of the two right sides of a right triangle is 17 and the area is 30cm & sup2;, then the length of the oblique side is?

Let the two feet be X. y and the hypotenuse be a
X+Y=17 XY/2=30
Pythagorean theorem: a * a = x * x + y * y = (x + y) * (x + y) - XY / 2 * 4 = 169
A=13
The length of oblique side is 13

The length of a right side of a right triangle is √ 3cm, and the length of the oblique side is √ 30cm. Calculate the area of the triangle

According to Pythagorean theorem, the length of the other right angle side = √ (30-3) = √ 27 = 3 √ 3
Then s = √ 3 × 3 √ 3 / 2 = 9 / 2 = 4.5 (CM & # 178;)
