Answer:

133°

Step-by-step explanation:

If the angle is "x"

We can say:

Complement of the angle is 90 - x

Supplement of the angle is 180 - x

Given, ANGLE IS 8 less than 3 times its SUPPLEMENT, so we can write:

x = 3(180 - x) - 8

So, now multiply and solve for x:

$x = 3(180 - x) - 8\\x=540-3x-8\\x=532-3x\\4x=532\\x=133$

Thus, the angle is 133 degrees

A motorcycle costs 12000. The value of the motorcycle deceases 6% each year. What is the rate each month

quester [9]

There are 12 months in a year and each year it decreases 6% so therefore each month it decreases .5%.

If you were asking the the amount it depreciates each month then you take .5% or .005 of 12000 which is 60 dollars a month.

The length of a rectangle is the width minus 8 units. The area of the rectangle is 9 units. What is the length, in units, of the

frez [133]

Length of rectangle is 1 unit

<u>Solution: </u>

Given that

Length of a rectangle is width minus 8 units.

Area of rectangle = 9 square units

Need to calculate the length of rectangle.

Let us assume width of rectangle = x

As Length is width minus 8,

Length of the rectangle = x – 8

$\text{ Area of rectangle }=\text{ width of rectangle }\times \text{ Length of the rectangle }$

$\text{ Area of rectangle }= x\times (x-8)$

$\text { Area of rectangle }=\left(x^{2}-8 x\right)$

As given that area of rectangle = 9 square units

$\begin{array}{l}{\Rightarrow x^{2}-8 x=9} \\\\ {\Rightarrow x^{2}-8 x-9=0}\end{array}$

On solving above quadratic equation for x, we get

$\begin{array}{l}{\Rightarrow x^{2}-9 x+x-9=0} \\\\ {\Rightarrow x(x-9)+1(x-9)=0} \\\\ {\Rightarrow (x-9)(x+1)=0}\end{array}$

When $x-9 =9, x = 9$

When $x + 1 = 0, x = -1$

As width cannot be negative, so considering x = 9

$\text{ Length of rectangle }= x-8 = 9-8 = 1 \text{ unit }$

Hence, Length of rectangle is 1 unit.
