Answer:
x= 90 degrees because AD is the perpendicular bisector and the angle bisector
y=86 degrees because 47+47+86=180

Step-by-step explanation:
Answer:
17900
Step-by-step explanation:
First term a = -19
common difference d = -15-(-19) = 4
number of terms, n = 100
sum of first 100 terms,
n/2(2a+(n-1)d)
= 100/2(2×(-19)+(100-1)4)
= 50×(-38+99×4)
= 50×358
= 17900
