Answer:
x=70
Step-by-step explanation:
sum is angles of a Pentagon=540°
x°+138°+2x°+80°+112°=540°
3x°+330°=540°
3x°=540°-330°
3x°=210°
3x°/3°=210°/3°
x=70

Answer:
D
Step-by-step explanation:
Recall that a⟌b means b/a. So, we want to find the expression: 20⟌4 and 4 ÷ 20. By examining, we see that D has those two expressions.
So, the answer is and we're done!
Answer:
Step-by-step explanation:
Let "n" be the second odd number in the sequence
(n - 2) + n + (n + 2) + (n + 4) + (n + 6) = 135
5n + 10 = 135
5n = 125
n = 25
23 + 25 + 27 + 29 + 31 = 135
One specific triangle CAN be made with those angles because of the 180 degree total.
