Answer:
the value of 43.7891 will obviously be 43.7891
Answer:
3+(px6)
Step-by-step explanation:
Answer: 63 degrees.
1. The Vertical Angles Theorem marks “x” as equivalent to its opposite angle (Angle A).
2. Angle A is apart of a 90-45-45 right triangle (since Angle B is 90 degrees).
3. Angle A and C are equivalent because of the 45-45-90 relationship.
4. Angle C is the vertical angle of the angle measuring 63 degrees.
5. So Angle X=Angle A=Angle C= 63 degrees.
Answer:



Step-by-step explanation:
Given


Solving (a1): The common difference (d)
d is calculated as

This gives:

Factorize:

Solving (a2): Sum of n terms
This is calculated using:

Substitute values for T1 and d


Factorize:


Solving (b): Sum of first 10.
In this case, n = 10
So:

becomes
