Draw a right triangle with 5 cm and 7 cm perpendicular sides. find its perimeter.

20.6 (3sf)

Step-by-step explanation:

a^2 + b^2 = c^2

5^2 + 7^2 = 74

c= root 74

5 + 7 + root 74 = 12 + root 74 = 20.6 (3sf)

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

the answer is: the length is 5/6 yards.
