Area=1/2bh
h=altitude
b=legnth of base
b is 3 times h
b=3h
divide by 3
b/3=h
area=1/2bh
subsitute b/3 for h
54=1/2(b)(b/3)
multiply bothsides by 2/1
108=b(b/3)
108=(b^2)/3
multipy both sides by 3
324=b^2
square root boh sides
18=b
legnth of base=18
Vpyramid=1/3 times area of base times height
volume=1/3 times 18 square inches times 4in
volume=6 square inches times 4in
volume=24 cubic inches
the volume is 24 cubic inches
Sin 27 degrees over 1= X over .8
Sin 27/1= X/8
Multiply sin(27) times .8
It equals. .36 or .4 if you have to round it to the nearest tenth
The LCD of the 2 fractions is 30 by multiplying the first fraction by 2 and the second fraction by 3 for example:
1/15 x 2/2 = 2/30
9/10 x 3/3 = 27/30
Which these 2 fraction equals up to 29/30 Hope this helps my dude ^^
