The delivery ramp at the corner cafe id a right triangle. the hypotenuse is 4 meters long. one leg is 3 meters long. what is the length of the other leg
f. sqrt 7 meters
g. sqrt 12 meters
h. 3.5 meters
j. 5 meters

f. sqrt 7 meters

Step-by-step explanation:

we use Pythagoras' theorem here,

let the unknown side be x,

therefore,

=> 3² + x² = 4²

=> x² = 16 - 9

=> x = √7 m

f. sqrt 7 meters

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem to solve.  We know the hypotenuse is 4 and one leg is 3.  We want to solve for the other leg.

a^2 +b^2 = c^2  where a and b are the legs and c is the hypotenuse.

Substituting into the equation

3^2 + b^2 = 4^2

9+b^2 = 16

Subtracting 9 from each side

9-9+b^2 = 16-9

b^2 =7

Taking the square root of each side

sqrt(b^2) = sqrt(7)

b = sqrt(7) meters

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
