The sum of the lengths would be the perimeter
Use a calculator to add the values of the sides and you'll have it
12 1/2
-10 3/5
=2 1/10
I think. if I am wrong I am sorry
Answer:

Step-by-step explanation:



Multiply both sides by 34:





Multiply both sides by 34:


<span>Brian and shadow to Z point math hypotenuse of a right triangle .
Tree and shadow to the right-angled triangle hypotenuse well .
Shadow length depends on the angle of incidence of solar prmieni . The angle of Padania , in both cases the same joke . So tangents hypotenuse same joke .
tg = a/b
Brian
a/b = 6ft/4ft = 1,5
A tree
a/b = a/20ft
a/20ff = 3/2 </span><span>We multiply the cross
2a = 60ft
a = 30tf
Answer : </span>The tree is 30 feet
