Answer:
A‘‘ (1,6)
Step-by-step explanation:
after a reflection about a horizontal line the x coordinates remain the same
the middle point of the segment AA’ lies on the line so it has y = -1
so we have
(y+y’)/2 = -1
y’ = -2 -y
y‘ = -2 -2 = -4
so A‘ (1,-4)
we can use the same reasoning to find the reflection about y = 1
x‘ = x
(y + y’)/2 = 1
y‘ = 2+4
y’ = 6
A‘‘(1,6)
Answer:
its so difficult how can I solve it please tell me
Answer:
circle,triangle, trapezium, polygon, squres, rectangle, cylinder,sphere, cone
Tan0 = opposite/adjacent
To find the opposite side you need to use Pythagoras Theorem.
Where
a^2 + b^2 = c^2
Rearrange for b^2 term
c^2 - a^2 = b^2
c=8 a=7
64-49 = 15
B is equal to square root 15 which is equal to length of opposite side.
Since Tan0 = opposite/adjacent
= root 15/7 is the answer
No a more reasonable answer would be close to 2.5
