Find the value of x of the two triangles.

x=20

Step-by-step explanation:

scale factor = 25÷20 = 5/4

16 × (5/4) = 20

x = 20

Step-by-step explanation:

since the shapes are congruent, their corresponding sides are proportional

8/10 = 16/x

8x = 160

x = 20

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.
