Answer:
a square, rectangle,trapezoid
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
a bearing is the angle in degrees measured clockwise from north.
Triangle ABC is a right triangle
Tan C = opp side / hyp
tan C = AB / CA
tan C = 30/30
tan C = 1
taking the inverse tan
tan ^ -1 tan C = tan ^ -1 ( 1)
C = 45 degrees
This is 90+45 degrees from North
135 degrees from north
Tan B = opp side / hyp
tan B = AD/BA
tan B = 45/30
tan B = 3/2
taking the inverse tan
tan ^ -1 tan B = tan ^ -1 ( 3/2)
D = 56.30993247
Add 180 degrees
180+56.30993247
236.3099325 from north
Answer:
= 25
Step-by-step explanation:
2 (-3)^2 - (4(-2) + 1)
2 (9) - (-8 + 1)
18 - (-7)
25
325 three hundred twenty-five
Let the interior angle be x.
x/(180-x) = 13/2
2x= 2340-13x
15x=2340
x=156
exterior angle= 180-156=24
Number of sides=360/24=15
15-sided polygon
