Question

Find the missing length of the triangle.

Answer 1

Let's find the hypotenuse.

7.2^2 + 9.6^2

51.84 + 92.16 = 144

√144(square root of 144) = 12, c = 12

Answer 2

12 =c

Explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

7.2 ^2 + 9.6 ^2 = c^2

51.84+92.16= c^2

144 = c^2

Taking the square root of each side

sqrt(144) = sqrt(c^2)

12 =c
