Aright triangle has legs of lengths 9 cm and 12 cm. calculate the length of the hypotenuse?

Length of hypotenuse is 15 cm

Step-by-step explanation:

If a,b are the legs of right triangle

and hypotenuse is c then according to Pythagorean theorem

taking square root ,we get

c = 15

therefore hypotenuse for given right triangle is 15 cm.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
