Sagot :

Answer:

Step-by-step explanation:

b/c this is an isosceles triangle  we know that either leg is the same length.. so we can use many trig functions  :)

SOH CAH TOA to remember how trig functions fit on the triangle...

we know the hypotenuse and the angle and we want to find the adjacent leg ( which for this triangle is also the opposite leg )

use Cos = Adj / Hyp

Hyp*Cos(45) = adj

16* [tex]\sqrt{2}/2[/tex] = adj

8*[tex]\sqrt{2}[/tex] = adj

each leg is the same  [tex]8\sqrt{2}[/tex]
