Answer:
10) 40
Step-by-step explanation:
just subtract 95 and 55
The triangle sum theorem says all 3 interior angles must equal 180 degrees.
so, 43 + 35 = 78. [ 180 - 78 = 102 degrees for the missing angles shared by the 2 triangles.
102 + 18 = 120. [180 - 120 = 60}
leaving the measure of Angle A as 60 degrees.
Answer:
All statements are true
Step-by-step explanation:
1. The statement 
is true, because 
is the sum of first 499 terms, 
is the sum of first 500 terms, and all these terms are positive, then the sum of smaller number of terms is less than the sum of larger number of terms.
2. The statement 
is true, because is the sum of first 500 terms, 
is 500th term and the sum of 500 terms is greater than the 500th term.
3. The statement 
is true, because 
is the sum of first 1 term that is exactly 
All statements are true.
