We know that:
limx→0
sin(x)/x
= 1.
and
cscx = 1/sinx
so,
<span>limx→0 x/sinx = 1</span>
Answer:
x =
; y = 2
Step-by-step explanation:
You have a 45 -45 - 90 triangle. There are two things to know"
1. The hypothenuse = leg × 
2. The legs are equal.
The hypothenuse is opposite the right angle that is "y" in this problem.
Hypothenuse = leg × 
= 
The legs are =
Therefore x = 
Well an example is 4x3x3 which equals 36 which is even
Answer:
3.5 m
Step-by-step explanation:
Use Pythagorean theorem to find the distance (d) the distance goes up the wall = adjacent to the angle 75° that is formed with the wall.
Length of ladder = the hypothenuse = 13.5 m
Thus, we would use:
Cos75 = adjacent/hypothenuse
Cos 75 = d/13.5
Multiply both sides by 13.5
13.5*cos(75) = d
13.5*0.2588 = d
3.4938 = d
d ≈ 3.5 m (nearest tenth)
