Answer:

The angle ZLK has a value of 75 degrees.

Step-by-step explanation:

We can calculate this as:

m\angle MLZ+m\angle ZLK=m\angle MLK\\\\(x+66)+(x+86)=130\\\\2x+152=130\\\\2x=130-152\\\\x=-22/2=-11\\\\\\m\angle ZLK=x+86=-11+86=75

We replace the angles values in the equation, as both angles that are formed with Z (MLZ and ZLK), when added, gives as the angle MLK. This allows us to calculate x. The value for x is -11.

Then, with the value for x we can calculate any of both angles.

Which expression is equivalent to the radical expression shown below when it is simplified?
babymother [125]

Answer:

\sqrt{\frac{3}{64} } in simplified form is \frac{\sqrt{3}}{8}

Step-by-step explanation:

We need to solve the expression

\sqrt{\frac{3}{64} }

We know that \sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}

and 64 = 8*8

Solving we get

=\frac{\sqrt{3}}{\sqrt{64}}\\=\frac{\sqrt{3}}{\sqrt{8*8}}\\=\frac{\sqrt{3}}{\sqrt{8^2}}\\=\frac{\sqrt{3}}{8}

So \sqrt{\frac{3}{64} } in simplified form is \frac{\sqrt{3}}{8}

How do you find the area of a triangle ?
katovenus [111]

Answer:

to find the Area of a Triangle, you have to multiply the base times the height of the triangle to find the Area.

Step-by-step explanation:

For example..

If the Base ( bottom part of the triangle) was 10 and the height ( the vertical line of the triangle) was 5, you would multiply them together to get 50. So 5o would be the area of the Triangle.

The file AutoResale contains mileage, age, and selling price for a sample of 33 Honda Accords. Click on the datafile logo to reference the data. The estimated regression equation is Selling price = 20385.25049 - 0.03739 Mileage - 686.33668 age. Round your answers to the nearest dollar. a. Estimate the selling price of a four-year-old Honda Accord with mileage of 40,000 miles.

answer :  ≈ $16144

Step-by-step explanation:

<u>Determine the selling price of a four-year-old Honda Accord with mileage of </u><u>40,000</u><u> miles.</u>

Given data :

Age= 4 year, Mileage=40,000 miles

Hence the selling price

= 20385.25049 - 0.03739 Mileage - 686.33668 age

=  20385.25049 - 0.03739(40,000)  - 686.33668 ( 4 )

= $16144.32
