Answer:
y=4
Step-by-step explanation:
Answer:
if you convert inches to cm...
Step-by-step explanation:
9inch=22.86cm
12inch=30.48cm
V=TTr²h
TT= 3.14
V= 3.14×22.86²×30.48
V= 50014.6cm³
if you don't convert inches to cm...
V=TTr²h
V=3.14 ×9×12
V=339.12cm³
This is an isosceles triangle, therefore we have two sides with the same length.
This sides are JM and MK; therefore:
JM=MK
JM=9x-18
MK=3x
Therefore:
9x-18=3x
9x-3x=18
6x=18
x=18/6
x=3
Part A:
Answer: x=3
Part B:
JM=9x-18=9(3)-18=27-18=9
Answer: JM=9
Answer:
A=45 square inches
Step-by-step explanation:
First find the height using Trig
Tan(45)=x/6
x=6tan(45)
x=6
Then area of a parallellogram is base x height so
A=7.5 x 6
A=45 square inches
The numbers are 10 and 7
X = 10
Y= 7
X + Y = 17
X - Y = 3
