<span>An <span>isosceles trapezoid<span> has both legs of equal length. LK = MN

Lower base angles are equal. ∠ K = ∠ N
Upper base angles are equal. ∠ L = ∠ M
Opposite angles are supplementary. ∠ K + ∠ M = 180°  

If you picture the top LM = 3 moving down to the bottom base KN, it makes two equal lengths on either side. 13 - 3 = 10
KH = 5
HN = 8

You can use the Pythagorean theorem to find the altitude (LH). 
8² + (LH)² = (√89)²
64 + (LH)² = 89
(LH)² = 89 - 64
(LH)² = 25
LH = 5

Tan(LKN) = 5/5
inverse trig function

∠LKN = 45°

The expression log 3 (x-4) is undefined for all values such that
suter [353]
Translate it

remember that log_a(b)=c translates to a^c=b
so we can say it equals y
so
log_3(x-4)=y translates to 3^y=x-4

we want to find the values of x that make it undefined
well, we know that 3^y must be greater than 0
so we do
it is defined for
x-4>0
add 4
x>4

it is defined for all values such that x>4
