x = 99 degrees.

Step-by-step explanation:

The angle in the triangle adjacent to 123 = 180 - 123 = 57 degrees.

m < x = 42 + 57 = 99 degrees.   ( by the external angle of triangle theorem).

A new car is purchased for 22400 dollars. The value of the car depreciates at 11% per year. To the nearest tenth of a year , how
m_a_m_a [10]

Answer:

t= 12.9 years

Step-by-step explanation:

Value after t years = initial value ( 1 - r )^t

Where,

Value after t years= $5000

Initial value = $22,400

r= depreciation rate = 11%

t= length of time (years)

Value after t years = initial value ( 1 - r )^t

5000 = 22,400 ( 1 - 0.11)^t

5000 = 22,400(0.89)^t

Divide both sides by 22,400

(0.89)^t = 5000 / 22,400

(0.89)^t = 0.2232

Take the log of both sides

t log 0.89 = log 0.2232

t= log 0.2232 / log 0.89

= -0.6513 / -0.0506

= 12.87

t= 12.9 years

Si el perímetro de el siguiente paralelogramo mide 80 M cuanto mide la base cuanto mide la altura y cuanto mide el área
topjm [15]

Answer:

<h2>The area of the parallelogram is 300 square meters. Its height (length) is 30 meters and its width is 10 meters.</h2>

Step-by-step explanation:

Assuming that the parallelogram is a rectangle, its perimeter would be defined as

P=2(w+l)

Where w is the width and l is the length.

But, P=80 \ m, so

80=2(w+l)\\w+l=40

Which means the sum of its dimensions is 40 meters.

Easily, its dimenions can be 10 meters and 30 meters.

So, its area would be

A= w \times l = 10 \times 30 = 300 \ m^{2}

Therefore, the area of the parallelogram is 300 square meters. Its height (length) is 30 meters and its width is 10 meters.
