Two right triangles are similar and have areas of 36 m and 144 m². If the hypotenuse of the larger triangle is 30 m long, what is the length of the hypotenuse of the smaller triangle?

18

Step-by-step explanation:

Find the scale factor: 144/36= 4. But scale factor of area is r^2=4=> r= 2

Hypotenuse of small triangle is:

36/x=2 => x=18

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
