Given that the perimeter of rhombus ABCD is 20 cm, the length of the sides will be:
length=20/4=5 cm
the ratio of the diagonals is 4:3, hence suppose the common factor on the diagonals is x such that:
AC=4x and BD=3x
using Pythagorean theorem, the length of one side of the rhombus will be:
c^2=a^2+b^2
substituting our values we get:
5²=(2x)²+(1.5x)²
25=4x²+2.25x²
25=6.25x²
x²=4
x=2
hence the length of the diagonals will be:
AC=4x=4×2=8 cm
BD=3x=3×2=6 cm
Hence the area of the rhombus wll be:
Area=1/2(AC×BD)
=1/2×8×6
=24 cm²
Answer:
D
Step-by-step explanation:
y intercept is b, so in the equation so far it is
y=mx+(5)
the slope is m, so
y=(-3)x+5
the answer is D.
75√109.5=1.46
1.2√79.1=65.92
5.2√9.16=1.76
17.1 =17.1
I don't know if you need the answer to how long the ladder is or what degree the ladder and ground form so I am going to give you both.
The ladder is 58.31 inches
The degree is 59.04
If you have any question let me know
Well, if 80% of 60 is 48, and 48x5 is 240, 80% of 60 is 240.
Answer: 240
Hope this helps! Xo
