Step-by-step explanation:
I have included a drawing of the triangle.
we can use Pythagoreans theorem.
a^2+b^2=c^2
So,
(4x)^2+(3x)^2=75^2
16x^2+9x^2= 5,625
we can add like terms.
25x^2 = 5,625
25 25
x^2 = 225
Square root both sides.
x = 15
so, leg of 4x is
4(15)= 60 m
leg of 3x
3(15)= 45 m
Hope this helps!
