Pythagoras Theorem:
hipotenuse²=side1² +side2²
a=is the longest side of the triangle (hypotenuse)
b and c: are the other two sides.
In this case:
hipotenuse²=side₁² + side₂²
side₁=a=16
side₂=b=28
c²=16²+28²
c²=256+784
c²=1040
c=√1040=32.2490....≈32.25
Answer: D. 32.25
Answer:
(1, -7)
Step-by-step explanation:
P(3,4)
3 up ---> y = 4 + 3 = 7
2 left ----> x = 3 - 2 = 1
new point (1, 7)
after 180 rotation around origin
point is (-1, -7)
now reflection over y-axis
(1, -7)
