The angle is obviously larger than a right angle because it is bending outwards. This means it is greater than 90°, so ∠2 must be an obtuse angle.
Answer:
20=3.19
1=0.16
Step-by-step explanation:
Rounded to the nearest cent
12.75/80 to get unit price
Then unit price multiplied by 20
<u>Answer:</u>
100
<u>Step-by-step explanation:</u>
Given :
Terms ( n ) = 100
First term ( a ) = 100
Series = > 100 + 98 + 96 .......
Common difference ( d ) = 98 - 100 = > - 2
We know sum formula:
S_n = ( n / 2 ) ( 2 a + ( n - 1 ) d )
= > S_100 = ( 100 / 2 ) ( 200 + ( 100 - 1 ) - 2 )
= > S_100 = 50 ( 200 - 198 )
= > S_100 = 50 ( 2 )
= > S_100 = 100
Therefore, sum of first 100 terms is 100.
Use the final digit to get the answer:
The final digit is 3, therefore the only two consecutive numbers that add and end in 3 is 6 and 7.
Using this logic, the only two numbers are 26 and 27
