To do this, use the formula: a^2+b^2=c^2
25+49=c^2
74=c^2
8.60=c

a² + b² = c²
5² + 7² = c²
25 + 49 = c²
74 = c²
8.60 = c

Use the Pythagorean Theorem: a^2+b^2=c^2
5^2+7^2=c^2
25+49=c^2
74=c^2
8.6023252670...=c

This is so easy-peesy.According to pythagoras theory,the length
of the square of the hypotenuse is equal to the squares of both the base and the altitude.Therefore I conclude that the length of
this given right triangle is approximately 8.60 cm.The actual
length of the hypotenuse is too long to type on this page

The length is the square root of the sum of the squares of the legs. So 25+49= 74. The square root is 8.60

Remember Pythagoras' theorem: c^2 = a^2 + b^2
Hence square root of 25 + 49 = your hypotenuse = 8.60

Pythagorean Theorem: a^2 + b^2 = c^2 3^2 + 8^2 = c^2 9 + 64 = c^2 c = sqrt(73) cm

hypotenuse^2 = 5^2 + 7^2 = 74
hypotenuse = sqrt(74) = 8.6

Pythagorean Theorem
c² = a² + b²
c² = √(5)² + (7)²
c² = √25 + 49
c³ = √74
c = 8.602325267 cm
