How do you find the width and length of a rectangle knowing ONLY the diagonal and the area?
For e.g we draw a rectangle with length and width of 4cm and 3cm respectively. So the diagonal would be of 5cm(using Pythagoras theorem) and area 12cm^2. Now using algebra we can find the dimensions of the rectangle,Look below: let length=x let width=y so: x*y=12----(1) x^2+y^2=5^2----(2) x^2+y^2=25 Now simplifying the above equations: x^2=25-y^2 ---->x^2*y^2=144 ---->(25-y^2)*y^2=144 25y^2-y^4=144 y^4-25y^2+144=0 let y^4=z^2 so: z^2-25z+144=0 by simplifying the above quadratic equation: z=(25+(25^2-4(1)(144))^(1/2))/2(1) , z= (25-(25^2-4(144))^(1/2))/2 z=16, z=9 when z=16, when z=9 so y=4 ,so y=3 Now verifying which magnitude is correct for y: 12/4=x ,12/3=x x=3 not correct, because y>x x=4 is correct, because x>y
An angle of 50 degrees in standard position has its terminal side in the first quadrant. What are the coordinates of point P on the unit circle?
Draw a picture of this you will see that you can form a triangle with the radius of the circle being 1. This is the hypotenus of the triangle Using trig, x = cos 50 y = sin 50 P is (x,y) = P is (cos 50,sin 50) = (0.643, 0.766)
Two angles of a a triangle measures 50 degrees and 75 degrees what is the measure of the third angle?
A triangle will always have a total of 180 degrees when adding all inside angles.corner x = 50corner y =75corner z = unknownx+y+z=180180-x-y=z180-50-75=zz=55 degrees
