H = height of triangle
b = length of triangle base
A = area of triangle
Recall the formula for area of a triangle :
A = 1/2 bh
Plug in what was given in the problem :
h = b - 5
A = 42
A = 1/2 bh
42 = 1/2 b (b-5)
Answer:
Negative five is in fact a rational number.
Step-by-step explanation:
Rational numbers can either be negative or positive. An irrational number would be pi (3.14159 etc.)
Euclid wrote 1 books related to math & logic.
He compiles all his studies in one treatise called ELEMENTS
Since the given line is <span>ll to the req. line, so
</span>x-2y=62y = x - 6
y = (1/2)x - 3
slope = 1/2
equation of the req. line is
y - y1 = m(x - x1)
y - 6 = 1/2(x - 1)
2(y - 6) = 1(x - 1)
2y - 12 = x - 1
2y = x -1 + 12
2y = x + 11
y = (1/2)x + 11/2
