Polar coordinates are written as the distance of the point to the origin and its angle of elevation around the unit cirlce.
Draw a right triangle with an angle of

and a hypotenuse with a length of 5.
You can use trigonometric ratios to find the legs of this triangle, which are the x and y coordinates of the point.

As for y...

Step-by-step explanation:
54^2 + a^2 = 90^2
2916 + a^2 = 8100
a^2 = 8100 - 2916
a^2 = 5184
take the square root of 5184
a = 72
you could have also guessed that its a 3 4 5 right triangle
all the sides are multiples of 3 4 or 5

Answer:
~ -4x+4y+10
Explanation:
~ We have to collect like terms such as all the x’s, y and the normal numbers.
~ Then add like terms together: x-5x, 4y plus nothing, 3+7
~ After adding them, you should get -4x+4y+10.
