Answer:
5/9
Step-by-step explanation:
first, find a common dominator. the 1/3 would turn into 3/9 if you multiply it by 3 to get that common dominator. then just subtract the numerator normally and you get 5/9 :)
sorry if my explanation doesn't make sense TwT
The first triangle has a perimeter of 4+6+10 = 20.
The 2nd longest side is 6/20 = 3/10 of the perimeter. In the larger triangle, the 2nd longest side will have length (3/10)*60 = 18.
_____
These side lengths mean the "triangle" is a line segment. That is, it has zero area.

Answer:
m<D = 26
Step-by-step explanation:
Exterior angles thm:
83 + 6x - 4 = 21x + 4
6x + 79 = 21x + 4
6x - 21x = 4 - 79
-15x = -75
x = 5
m<D:
6x - 4
6(5) - 4
30 - 4
26

Answer:
cot(θ) = 24/7
Step-by-step explanation:
A suitable calculator can answer this nicely.

Perhaps you're expected to remember relevant trig identities.
tan(θ)^2 = sec(θ)^2 -1
cot(θ) = 1/tan(θ)
__
cot(θ) = 1/√(sec(θ)^2 -1)
cot(θ) = 1/√((25/24)^2 -1) = 24/√(25^2 -24^2) = 24/√49
cot(θ) = 24/7
