Answer:
A letter T is folded vertically through the middle.
Step-by-step explanation:
Reflectional symmetry refers to the symmetry of line that divides the given shape into two equal halves. The halves represent the mirror reflection of each other. The line of symmetry is drawn to show the reflection and it acts as a mirror. For the letter 'T', the reflectional symmetry will be drawn vertically in the middle of the letter. The line divides the letter into two equal halves with mirror images.
Answer:
a.
Step-by-step explanation:
i don't know the explanation step by step
You can check using the Pythagorean Theorem: a^2+b^2=c^
a=10
b=41
c=42 (because it is longest)
10^2+41^2=42^2
100+1681=1764
1781=1764
Since they are not equal, this is not a right triangle

is the angle of depression from the vertical cliff.
Option: A
Step-by-step explanation:
Given that, Height of the cliff (opposite side) = 40m
Distance of object from the base of the cliff (adjecent side) = 59.3m
To find the angle of depression of the object. From trigonometric rule in a right angled triangle, we know that 
Angle of depression = 
Therefore, the angle of depression to the object is .
