How do I find the midpoint

Hunter-Best [27]

To find the midpoint of a line use the midpoint formula which is M = (x1+x2/2 , y1 +y2/2) After plugging in the coordinates for your variables you should get (-1+5/2, -1+2/2) This simplifies to (2, 1/2) which is the coordinates for the middle point of the base XY.

From a boat on the lake, the angle of elevation to the top of a cliff is 26°35'. If the base of the cliff is 85 feet from the bo

Trava [24]

Check the picture below

now, 26°35' is just 26bdegrees and 35 minutes

your calculator most likely will have a button [ ° ' " ] to enter degrees and minutes and seconds

there are 60 minutes in 1 degree and 60 seconds in 1 minute

so.. you could also just convert the 35' to 35/60 degrees

so $\bf 26^o35'\implies 26+\frac{35}{60}\implies \cfrac{1595}{60}\iff \cfrac{319}{12}
\\\\\\
tan(26^o35')\iff tan\left[ \left( \cfrac{391}{12} \right)^o \right]$

now, the angle is in degrees, thus, make sure your calculator is in Degree mode
