One side of a triangle is 2 times the second side. the third side is 5 ft longer than the second side. the perimeter of a triangle is 81 ft. find the length of each side.
hello from mrbilldoesmath!
per the attachment,
cos(30 ) = n/ 32 => n = 32 cos(30) = 32 (sqrt(3)/2) = 16 sqrt(3)
area of shaded triangle =
area triangle dbc =
area triangle adc - area triangle abd =
1/2 (n) * (m + 40) - 1/2 n * m =
1/2 n*m + 1/2 (40n) - 1/2 n*m =
20 ( 16 sqrt(3)) = as n = 16 sqrt(3)
the length, in feet, of a rectangular rug is represented by the expression . the width, in feet, is represented by the expression
the perimeter of the rectangle is
thus, the perimeter is
a. this is the arithmetic sequence, because
the first term of this sequence is and the difference is 0.3.
b. since this is not arithmetic sequence.
c. since this is not arithmetic sequence.
d. since this is not arithmetic sequence.
