⌒DE = 110°
⌒AC = 85° + 25° = 110°
Both arcs have the same measurement; so the chords are the same.
Answer:
There are 18 odd numbers
Step-by-step explanation:
1,3,5,7,9,11,13,15,17, 19,21,23, 25,27,29,31,33,35
The two numbers added up is equal to 17 times 2 which is 34
34-11 is 23
The rule for the reflection is (x,y,z) → (-x,y,z) so P' = (1, 2, 0) for example.
<span>Then the rule is (x,y,z) → (x + 2, y + 4, z - 3) so P'' = (3, 6, -3) </span>
Answer:
<em> = n² + 4n ; n = 11 </em>
Step-by-step explanation:
= 
[2 
+ (n - 1)d]
~~~~~~~~~
= 5
d = 7 - 5 = 2
= [ 2(5) + 2(n - 1)] = ( 8 + 2n ) = 4n + n²
<em> = n² + 4n</em>
n² + 4n = 165
n² + 4n - 165 = 0
(n + 15)(n - 11) = 0 ( n ≥ 0 ) ⇒ <em>n = 11</em>
