Aright triangle has a hypotenuse of length 7 mm and one leg of length 3 mm. how long is the other leg? 12.6 mm 2 mm 4 mm 6.3 mm

  Option D is the correct answer.

Explanation:

 By Pythagoras theorem  we have

               Hypotenuse² = Base² + Perpendicular²

 Here hypotenuse = 7 mm

 Let us consider other leg length given as base length

 Base = 3 mm

 So we have

                     7² = 3² + Perpendicular²

            Perpendicular² = 40

            Perpendicular = 6.3 mm

 Other leg is 6.3 mm long.

  Option D is the correct answer.

6.3mm

Step-by-step explanation:

just took the test

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
