Answer:
384 sq mm
Step-by-step explanation:
Remember that the diagonals of a rhombus are perpendicular bisectors of each other.
So, one side of the rhombus, half the longer diag and half the shorter diag form the 3 sides of a right triangle
with the rhombus side being the hypotenuse.
In this case, let the shorter diagnoal be x mm. In the right triangle,
Hypotenuse = 20
One side = 32/2 = 16
Other side = x/2
Applying Pythagoras principle,
[ check the file attatched ] (taking only the positive square root)
So the shorter diagonal = 12*2 = 24 mm
Area of the rhombus is given by the formula (1/2)*d1*d2 where d1, d2 are the 2 diagonals.
Here, the area = (1/2)*32*24 = 32*12 = 384 sq mm
The bigger number is always first
Answer:
A- Quadrant one.
B- Quadrant three.
Step-by-step explanation:
So, the quadrants go counter-clockwise, starting at the top right which is Quadrant one. Therefore, A is in one. Using that information, we can assume that B is in Quadrant three.
$25
$5 is one fifth, so 5x5 is 25
Answer:
x=5 x=3
Step-by-step explanation:
f(x) = x^2 - 8x+ 15
Factor
What two numbers multiply to 15 and add to -8
-5*-3 = 15
-5+-3 = -8
f(x) = (x-5) (x-3)
Setting equal to 0
0= (x-5) (x-3)
Using the zero product property
x-5 =0 x-3=0
x=5 x=3
