Explanation:
638.8 is the result of evaluating the expression ...

Any scientific or graphing calculator or spreadsheet can compute this for you. (You may need to be careful to set <em>Degrees mode</em> for the angles.)
the answer is 11123475
Step-by-step explanation:
1+1=1
Answer:
B(3.5, 0.5)
Step-by-step explanation:
Given:
A(5,5), Xa=5, Ya=5
C(3,-1), Xc=3, Yc=-1
To find point B, we can use the partition rule, where AB = 3BC, so AB occupies k=3/4 of the distance AC.
B(x,y) = ((1-k)Xa+kXc, (1-k)Ya+kYc)
=(Xa/4+3Xc/4, Ya/4+3Yc/4), substitute values
=(5/4+3*3/4, 5/4+3*(-1)/4)
=(14/4,2/4)
=(3.5, 0.5)
To solve this problem you must apply the proccedure shown below:
1. You know that the sum of the angles is
degrees. Therefore, you must sum them and solve for
:

degrees
2. Therefore, the angles are:
degrees
degrees
The answers are:
