Answer:
<u>40°</u>
Step-by-step explanation:
Answer:
Step-by-step explanation:
use the distance formula.
x1=-1
x2=1
y1=4
y2=-2
d=√((x2-x1)^2+(y2-y1)^2)
d=√(30) or 5.4772
Answer:
15) x = 20
16) y = 45°, z = 30°
17) all 4 corners = 90°, all 4 sides are equal length, diagonals are perpendicular, diagonals bisect the corner angles.
We can't do the extra credit because we do not have a relationship about the side lengths. We just have angle information.
Step-by-step explanation:
15) 2x + 8 = 3x - 12
x = 20
16) 2y = 90°
y = 45°
3z = 90°
z = 30°
