One of the legs of a right triangle measures 5 cm and the other leg measures 8 cm. Find the measure of the hypotenuse. If necessary, round to the nearest tenth.

9.4cm

Step-by-step explanation:

by pythagoras theorem,

a^2 + b^2 = c^2

5^2 + 8^2 = c^2

c^2 = 89

c = √89 = 9.433981 ≈ 9.4

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
