How would I solve this

MariettaO [177]

Answer:

5√5

Step-by-step explanation:

Hypotenuse (h) = 15

perpendicular (p) = 10

base (b) = ?

We know by using Pythagoras theorem

b = √h² - p²

= √ 15² - 10²

= √ 125

= 5√5

Solve (5 x/3) (5 x/5) =54

Phoenix [80]

Answer:

$-\frac{9\sqrt{10} }{5}$ , $\frac{9\sqrt{10} }{5}$

Step-by-step explanation:

$(5*\frac{x}{3}) * (5*\frac{x}{5} ) = 54\\$ calculate the product

$\frac{5x}{3} * x =54$ multiply

$\frac{5x^{2} }{3} = 54$ multiply both sides by $\frac{3}{5}$

$x^{2} =\frac{162}{5}$ separate into two solutions

x = ± $\frac{9\sqrt{10} }{5}$
