Find The T value for point that splits segment EF in half if point E is located at (5,-2) and point F is located at (-1,3).

Tanzania [10]

The formula of a midpoint between two points:

$M\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)$

We have:

$(5,\ -2)\to x_1=5,\ y_1=-2\\\\(-1,\ 3)\to x_2=-1,\ y_2=3$

Substitute:

$\dfrac{5+(-1)}{2}=\dfrac{4}{2}=2\\\\\dfrac{-2+3}{2}=\dfrac{1}{2}$

Answer: $T\left(2,\ \dfrac{1}{2}\right)$

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>
