Answer: 8
because its going up by 8
8+8=16
16+8=24
24+8=32
8,16,24,32

Step-by-step explanation:
D, it has a right angle and it shows us that the hypotenuse is congruent and the leg is also congruent.
Answer:
the 1/2 part of it is 1/2
Step-by-step explanation:
Using Gauss's method
Total number of terms = [15-(-129)]/4+1=36+1=37
Add
S=15+11+7+....-125-129
S=-129-125-...+7+11+15
--------------------------------
2S=-114-114-114...(37 times)
=>
sum=S=(1/2)*(-114)*37=-2109
Using AP, T(n)=15+11+7+....-129
T(n)=19-4n => T(1)=15, T(37)=-129
S(n)=(1/2)(37)(T(1)+T(37)=(1/2)37(15-129)=2109
