Answer:
y=0
Step-by-step explanation:
Definition:An expression is undefined at the value(s) at which the denominator equals zero.
We are to determine the value of y that makes the expression undefined.
We equate the denominator to zero and solve for y.
Therefore, at y=0, the given expression is undefined.
60° = radians
To convert from degrees to radians
radian measure = degree measure ×
Thus 60° in radian measure
= 60 × ( divide ( cancel) 60 and 180 by 60 )
=
45x393=17685
45/393=.1145
1.3
Friend is wrong
Given:
friend's claim: height of his building is more than 1.50 times the height of yours
line of sight to the top edge of the other building makes an angle of 21° above the horizontal
line of sight to the base of the other building makes an angle of 52° below the horizontal
Solution:
Let A be the height of your building is A
Let B+A his building is B higher than yours.
Let the distance between the buildings is x.
then
tan 52 = A/x
tan 21 = B/x
A/B = tan 52 / tan 21
= 1.27994 / 0.38386
A/B = 3.33
(A + B) / A = 1.5 0
A/A + B/A = 1.50
1 + B/A = 1.50
B/A is basically (B/x) / (A/x)
So
1+ 3.33 / 3.33
= 4.33/3.33
= 1.3
Since 1.3 is not equal to 1.5
Hence the friend's claim is wrong.
