Standard form : Ax + By = C
y = 2/3x + 1
-2/3x + y = 1....multiply by -3
2x - 3y = -3 <=== standard form
Let the length of unknown side be x
So, hypotenuse = 2x + 1
By pythagorean theorem ie , a² = b² + c²
(2x + 1)² = x² + 15²
4x² + 1 + 4x = x² + 225
3x² + 4x -224
(3x +28)(x-8)
x = -9.33 , 8
Since, length can't be negative
x = 8
∴Unknown side length = 8 m
Length of hypotenuse = 2 x 8 + 1 = 17 m
Hope it helps now.
Answer:
3.42
Step-by-step explanation:
41/12 is 3.42
Answer:
21 kilometers
Step-by-step explanation:
Let the height be . Then, the length of the base is . The formula for the area is of the triangle is given by base*height/2. Therefore, the area of the triangle is equal to , which is in turn equal to 441. Since must be positive, then , meaning that the height is kilometers.
