Answer:
19 lawns
Step-by-step explanation:
well 64.99 is about $65
so you would need to mow atleast 19 lawns (this does not included tax XD)
Not sure for the others but a is 55 cause ps is half a circle witch is 180 and pt is 125 so just subtract 180 - 125 =55
Given:
Base of a right triangle = 7 in
Height of a right triangle = a
Hypotenuse = 16 in
To find:
The length of side a.
Solution:
Using Pythagoras theorem:



Subtract 49 from both sides.


Taking square root on both sides, we get
a = 14.4
The length of side a is 14.4 in.
Step-by-step explanation:
We have cartisean points. We are trying to find polar points.
We can find r by applying the pythagorean theorem to the x value and y values.

And to find theta, notice how a right triangle is created if we draw the base(the x value) and the height(y value). We also just found our r( hypotenuse) so ignore that. We know the opposite side and the adjacent side originally. so we can use the tangent function.

Remeber since we are trying to find the angle measure, use inverse tan function

Answers For 2,5

So r=sqr root of 29

So the answer is (sqr root of 29,68).
For -3,3


Use the identity

So that means

So our points are
(3 times sqr root of 2, 135)
For 5,-3.5


So our points are (sqr root of 37.25, 35)
For (0,-5.4)

So r=5.4

So our points are (5.4, undefined)
