Answer:
34.88 feet
Step-by-step explanation:
The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
We want to find the length of the side adjacent to the measured angle. The hypotenuse is the ladder length.
cos(29.32°) = distance/(40 ft)
distance = (40 ft)cos(29.32°) ≈ 34.876°
The base of the ladder is about 34.88 feet from the building.
_____
<em>Additional comment</em>
It extends about 19.59 feet up the side of the building.
We know CXD form a 90 degree angle, plus 32 that is angle BXC
90+32=122
We also know XH bisects this angle, which means it cut it in half,
122/2= 61
Answer: 61

Answer:
0 handshakes
Step-by-step explanation:
There are 8 women of different heights.
Let the eight women be A, B, C, D, E, F, G and H
Assume A is taller than B and A decides to shake hands with B, B will refuse because A is taller. If this happens across the eight women then there will be 0 hand shakes.
If this assumption is taken out, we have 7+6+5+4+3+2+1 = 28
