The length of the radius would sqrt(1+4), or sqrt(5).
2
The angle would be in Quadrant II and would be arctan ------ , or arctan (-2).
-1
Find this angle using a calculator or table.
Then you end up with -1+2i = sqrt(5) angle arctan(-2). The angle would be + and measured from the + horizontal axis.
Answer:
0'=(0,3)
Step-by-step explanation:
P'=(-5+5,7-5)=(0,3)
If you would like to know what percent of 75 is 33, you can calculate this using the following steps:
x% of 75 is 33
x% * 75 = 33
x/100 * 75 = 33 /*100/75
x = 33 * 100 / 75
x = 44%
Result: 44% of 75 is 33.
B) right angle triangle
angles in a triangle add up to 180 degrees
31+59=90
180-90=90
90 degrees is a right angle
