The hypoténuse of a right triangleis 34 in. One leg of the triangle is 14 inches less than the other leg. In simplified form, wh
liberstina [14]

Answer: the length of one leg is 30 inches and the leg of the other leg is 16 inches.

Step-by-step explanation:

Let the other leg of the triangle be x inches.

One leg of the triangle is 14 inches less than the other leg. This means that the length of this leg of the triangle is (x-14) inches.

The length of the hypothenuse of the right triangle is 34 inches.

The diagram of the triangle, showing it's dimensions is shown in the attached photo.

Applying Pythagoras theorem,

Hypothenuse^2 = adjacent^2 + opposite ^2

The simplified equation that can be used to find the lengths of the legs is

34^2 = (x-14)^2 + x^2

1156 = (x-14)(x-14) + x^2

1156 = x^2 - 14x - 14x + 196 + x^2

1156 = 2x^2 -28x +196

2x^2 -28x +196 - 1156 = 0

2x^2 -28x - 960 = 0

Dividing through by 2,

x^2 -14x - 480 = 0

x^2 +16x - 30x - 480 = 0

x(x+16)-30(x+16) = 0

(x + 16)(x - 30) = 0

x+16 = 0 or x-30= 0

x = -16 or x = 30

So x = 30 inches( because it cannot be negative)

One leg = x-14 = 30-14 = 16 inches

frozen [14]

Answer:

$12

Step-by-step explanation:

first we multiply the candies by the weight to find out the total weight

60* 25= 1500g

1500g to kg = 1500/1000 = 1.5kg

so its going to be 1.5kg * 8

1.5* 8 = 12
