<span>r²sin²θ = 16rcosθ </span>
<span>rsin²θ = 16cosθ </span>
<span>r = 16cosθ / sin²θ </span>
<span>r = 16cotθcscθ</span>
For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
Doing the multiplication we have:

From here, we clear the value of x.
We have then:

Therefore, we have:
Answer:
7 times 1/7 equals 1
12^2+x^2=15^2
144+x^2=225
- 144 -144
=81= 9
X=9

Answer:
See Explanation
Step-by-step explanation:
According to the Question,
Steps of construction:
- Step I - Draw a line segment AB = 7 cm with the help ruler.
- Step II - with vertex A, by using compass take more than half of AB and draw arcs, one on each side of AB.
- Step III - with vertex B, by using a compass with the same length, cut the previous arcs at X and Y respectively.
- Step IV - with help of the ruler join the points X and Y Thus XY is the perpendicular bisector of line AB.
