Answer is TRUE.

A horizontal line test will ensure that the function is one-to-one. This means each y value is paired with exactly one x-value.

If this is true for the function, we can ensure that the inverse will have exactly one x value paired with only one y value and thus will pass the horizontal line test.

Sine, cosine, and tangent to calculate the height of the buildings in the diagram below.
DiKsa [7]

Answer: Around 68.0858 m

Step-by-step explanation:

  • Set the height of 37°-53°-90° triangle as x
  • Set the height of 50°-40°-90° triangle as y
  • The horizontal side both triangles share = 35

To find x                            To find y  

tan(37)=\frac{x}{35} \\\\35tan(37)=x\\\\x=26.37439...                     tan(50)=\frac{y}{35} \\\\35tan(50)=y\\\\y=41.7113757...

To find the height of the building, add the x-value and y-value:

x+y=26.3744+41.7114=68.0858  

<em>I hope this is correct o_o</em>
