omeli [17]

<span>x = length cm
y = width cm
---
y = 3
xy = area
xy = 1035
x*3 = 1035
x = 1035/3
x = 345

so the answer is 345</span>

The rule to remember about generating the perpendicular family to a line is we swap the coefficients on and x and y, remembering to negate one of them. Then the constant is set directly from the intersecting point.

So we have

y = 3x + 2

-3x + 1y = 2

Swapping and negating gets the perpendiculars; the constant is as yet undetermined.

1x + 3y = constant

Since we want to go through (0,2), we could have just written

x + 3y = 0 + 3(2) = 6

3y = -x + 6

y = (-1/3) x + 2

Answer:

a. $x=10 \textdegree$

b.

$m\angle L=39\textdegree\\\\m\angle M=51\textdegree\\\\m\angle K=90\textdegree$

Step-by-step explanation:

a. We know that angles in a triangle add up to 180°.

-The right angle triangle in the right triangle has a measure of 90°.

We can therefore equate our angles to 180° and solve for x;

$180=\perp\angle+(2x+19)+(3x+21)\\\\180=90+(2x+19)+(3x+21)\\\\90=5x+40\\\\5x=50\\\\x=10\textdegree$

Hence, the angle measure is x=10°

b. Having calculated the value of x from a above as x=10°, we can substitute to find the measures of the two acute angles:

$m\angle L=(2x+19)\textdegree\\\\=(2\times 10+19)\textdegree\\\\=39\textdegree\\\\m\angle M=(3x+21)\textdegree\\\\=(3\times 10+21)\textdegree\\\\=51\textdegree$

Since, the m∠K is a right angle, it measures 90°
