The polar coordinates of a point are 3π 4 and 7.00 m. What are its Cartesian coordinates (in m)? (x, y) = 6.06,−3.5 m

a)

b)

Step-by-step explanation:

Polar coordinates are represented as: , where 'r' is the length (or magnitude) of the line, and '' is the angle measured from the positive x-axis.

in our case:

to covert the polar to cartesian:

we can plug in our values:

the Cartesian coordinates are:

(b) to convert (x,y) = (6.06,-3.5)

we'll use the pythagoras theorem to find 'r'

the angle can be found by:

to convert radians to degrees:

writing in polar coordinates:

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
