Find the angles of x and y​
Gnesinka [82]

or, x=180

or,34=180

or,180-34

or x=146

Now,

or, y=146

or,18=146

or146-18

or, y=128

there is x is 34 and its all side angle is 180 degree So put x =180 and then put x value is 34 =180 and there is no values in front of 34 so there will be + and if +so in another side it will be - and then after put 180-34=146

The volume of a cylinder is 770 cm. It's height is 5 cm. Find its approximate radius.
Alinara [238K]

Hey there,

The equation for the volume of a cylinder is V = πr²h.

The first step into finding the radius is to plug in what you already know into the equation:

  • 770 = πr²5

We divide both sides by 5:

  • 154 = πr²

Now we divide both sides by π:

  • 49.0197224723 = r²

Finally we just do the square root of 49.0197224723:

  • 7.0014086063 = r

The radius therefore would be about 7cm.

Hope I helped,

Jenny watched a movie about aliens who never stop growing. Every alien is 10 centimeters tall at birth and grows exactly 8 centi
ss7ja [257]

Answer:

h = 10 + 8y

Step-by-step explanation:

Given that :

Height of ght if all alien at birth = 10cm

Growth rate per year = 8 cm

Let:

y = number of years since birth

h = alien's height in centimeter

Relationship between h and y

h = Initial height + (growth rate per year*number of years)

h = 10 + 8y
