Answer:
The length of LM,hypotenuse is 55.866ft
Step-by-step explanation:
Given that LN=39ft and MN=40ft so you can solve it using Pythogoras' Theorem:
side²+side² = hypo²
LN² + MN² = LM²
hypo² = 39²+40²
= 3121
LM = √3121
= 55.866ft (3d.p)
A. a=145 b=35 c=145 d=145 e=35 f=145 g=35
b. These are the pairs of vertical angles: a & c, b & 35, d & f, e & g.

The distance from the top of the mirror to the ceiling once the mirror is hung on the wall is 21 inches
The dimension of the mirror is given as:


From the center of the mirror to the floor of the wall, the distance is:

So, the distance to the top of the mirror will be:

Substitute 24 for height


Convert feet to inches



The distance from the top of the mirror to the ceiling is the difference between the height of the wall and 75 inches.
So, we have:

Convert feet to inches



Hence, the distance is 21 inches
