Answer:
tan²A
Step-by-step explanation:
1+tan²A/1+cot²A Simplify 1+tan²A first
sec²A/1+cot²A Now simplify 1+cot²A
sec²A/csc²A Simplify sec²A and csc²A
/
Simplify the fraction
sin²A/cos²A = tan²A

Straight lines are 180 degrees and angle BCD is 110 degrees, and also AB and CB are the same which means 180-110=70 and 70 divided by 2 is 45 degrees so m angle A =45 degrees and m angle B= 90 degrees and ACB is 45 degrees
It looks like you're asked to find the value of y(-1) given its implicit derivative,

and with initial condition y(2) = -1.
The differential equation is separable:

Integrate both sides:


Solve for y :



![y = -\dfrac1{\sqrt[3]{3x+C}}](https://tex.z-dn.net/?f=y%20%3D%20-%5Cdfrac1%7B%5Csqrt%5B3%5D%7B3x%2BC%7D%7D)
Use the initial condition to solve for C :
![y(2) = -1 \implies -1 = -\dfrac1{\sqrt[3]{3\times2+C}} \implies C = -5](https://tex.z-dn.net/?f=y%282%29%20%3D%20-1%20%5Cimplies%20-1%20%3D%20-%5Cdfrac1%7B%5Csqrt%5B3%5D%7B3%5Ctimes2%2BC%7D%7D%20%5Cimplies%20C%20%3D%20-5)
Then the particular solution to the differential equation is
![y(x) = -\dfrac1{\sqrt[3]{3x-5}}](https://tex.z-dn.net/?f=y%28x%29%20%3D%20-%5Cdfrac1%7B%5Csqrt%5B3%5D%7B3x-5%7D%7D)
and so
![y(-1) = -\dfrac1{\sqrt[3]{3\times(-1)-5}} = \boxed{\dfrac12}](https://tex.z-dn.net/?f=y%28-1%29%20%3D%20-%5Cdfrac1%7B%5Csqrt%5B3%5D%7B3%5Ctimes%28-1%29-5%7D%7D%20%3D%20%5Cboxed%7B%5Cdfrac12%7D)

Answer:
the building is thirty feet tall
Step-by-step explanation:
so make a ratio of shadow to joey
5:45
simplify that to
1:9
so you can now divide 270 by nine
30
the building is thirty feet tall
