Step-by-step explanation:
Let us consider the length of a line segment to be 'x'
Let the other line segment be 'y'
One line segment is 12 less than twice the length of other segment.
X = 2y - 12
The sum of both the lengths = 69cm
X + Y = 69
X = 69 - Y
Substitute the X value in the first equation
X = 2y - 12
69 - Y = 2Y - 12
- Y - 2Y = -12 -69
- 3Y = - 81
3Y = 81
Y = 81/3
Y = 27 CM
Length of One of the line segment is 27cm
The length of the other line segment 'x'
is
X= 2y - 12
X = 2(27) - 12
X = 54 - 12
X = 42cm
The length of the line segments are 42cm and 27cm.
Answer:
300ft
Step-by-step explanation:
From any one vertex, you can draw a line that is perpendicular<span> to the opposite base — that's the </span>altitude<span> to this base. Any </span>triangle<span> has three </span>altitudes<span> and three bases. You can use any one </span>altitude<span>-base pair to </span>find<span> the area of the </span>triangle<span>, via the formula A = (1/2)bh </span>
