Find the area and perimeter.

Step-by-step explanation:

This a 30° 60° 90° special triangle and the side lengths would be 4 4√3 8

To calculate the primeter of a triangle we add all three side lengths together therefore the perimeter of this triangle is 4 + 4√3 + 8 = 12 + 4√3 or 18.9 (because 4√3 is = 6.9 approximately)

We calculate area of a triangle by multiplying height to the base and that divided by two

The height given here is 4√3 and base is 4

4√3 × 4 ÷ 2 = 8√3 ft^2

is should be y = 5x

correct me if im wrong

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
