Answer:
108 deg
Step-by-step explanation:
Since sides DB and CD are congruent, then opposite angles are congruent.
m<C = m<B = 36
m<B + m<C + m<D = 180
36 + 36 + m<D = 180
m<D = 108
Answer:
I'm pretty sure it is the second one because > means it won't be filled in and it means greater than so greater than 2
She would’ve ran 54.25 miles because 1.75 multiplied by 31 is 54.25. Hope this helps:)

Answer:
∑(1+8n)
Step-by-step explanation:
Given:
series : 9+17+25+...
As first term= 9
for n=1, expression should comes out to be 9
for 2+7n:
2+7(1)=9
for (n+8)
1+8=9
for (1+8n)
1+8(1)=9
all is true
now for n=2, the expression's outcome be 17
for 2+7n:
2+7(2)=16
comes wrong
for (n+8)
2+8=10
comes wrong
for (1+8n)
1+8(2)=17
come right
Also for n=3, (1+8(3))=25
Hence correct expression is ∑(1+8n) !
