Tanα=h/x, tanß=h/(x+88)
solving both for x
x=h/tanα, x=h/tanß-88, since x=x
h/tanα=h/tanß-88
h/tanß-h/tanα=88
(htanα-htanß)/(tanα*tanß)=88
h(tanα-tanß)/(tanα*tanß)=88
h=88(tanα*tanß)/(tanα-tanß)
Since α=32 and ß=22...
h=88(tan32*tan22)/(tan32-tan22)
h≈85.3 feet
4is thex the yintercept is -8
Without knowing anything else about 
, neither of these need be true.
Suppose
Then (I) isn't true because, while the limit exists as 
and is equal to 7, we have 
, so is not continuous there.
(II) also true because is not differentiable at 
; that is,
but
which means the derivative does not exist at .
Answer:
10 1/9
Step-by-step explanation:
To make it easier to answer, make both of them into an improper fraction
4 1/5 = 21/3
1 4/9 = 13/9
Now we can multiply them easier
21/3 x 13/9 = 273/27
27 goes into 273 10 times and the left over is 3 so the mixed fraction would be
10 3/27, to simplify
10 1/9
Answer:
Step-by-step explanation:
Remark
All of the given listed figures have the property of 4 sides and 4 angles. There is also some relationship between the angles or pairs of angles. Only the square follows the same path. The others cannot be chosen because the sides differ and the angle properties are quite different.
Answer: <u>Square</u>
