The sum of the interior angles in a triangle is 180 degrees. Therefore, if we add up all of these angles, they must be equal to 180.

64 + 85 + (4x + 27) = 180

176 + 4x = 180

4x = 4

x = 1

Let's check our answer!

4(1) + 27 = 31

31 + 85 + 64 = 180

180 = 180

Hope this helps!! :)

Answer:

x=1

Step-by-step explanation:

The sum of the angles in a triangle is 180

64+ 85+ 4x+27 = 180

Combine like terms

4x+176=180

Subtract 176 from each side

4x+176-176 =180-176

4x = 4

Divide by 4

4x/4 = 4/4

x=1

a solid consists of cylinder surmounted by a right circular cone. The height of the cone is 2h. If the volume of the solid is 3

Mademuasel [1]

Answer:

height of cylinder = 4/3 h

Step-by-step explanation:

The solid has a cylinder surmounted with a cone .Therefore, the volume of the solid is the sum of the cone and the cylinder.

volume of the solid = volume of cylinder + volume of cone

volume of the solid = πr²h + 1/3πr²h

let

height of the cylinder = H

recall

the height of the cone = 2h

volume of the solid = πr²h + 1/3πr²h

3(1/3πr²2h) = πr²H + 1/3πr²2h

2πr²h = πr²H + 2/3 πr²h

πr²(2h) = πr²(H + 2/3 h)

divide both sides by πr²

2h = H + 2/3 h

2h - 2/3h = H

H = 6h - 2h/3

H = 4/3 h

height of cylinder = 4/3 h

Find the value of f(-1) for the function below

mrs_skeptik [129]

Put the value of x = -1 to the equation of a function f(x):

$f(x)=\dfrac{2}{3}\times3^{3x+12}\\\\f(-1)=\dfrac{2}{3}\times3^{3(-1)+12}=\dfrac{2}{3}\times3^{-3+12}=\dfrac{2}{3}\times3^9=\dfrac{2}{1}\times3^8=13,122\to\boxed{B.}$

Drag the tiles to the correct boxes to complete the pairs.

navik [9.2K]

A. 9

B. 24

C. 6

D. 16

Step-by-step explanation:

Given ratios are;

A. 2 : 3 = 6 : x

Product of mean = Product of extreme

$6*3=2*x\\18=2x\\2x=18$

Dividing both sides by 2

$\frac{2x}{2}=\frac{18}{2}\\x=9$

B. 4 : 7 = x : 42

Product of mean = Product of extreme

$7x=168$

Dividing both sides by 7

$\frac{7x}{7}=\frac{168}{7}\\x=24$

C. 2x : 48 = 3 : 12

Product of extreme = Product of mean

$2x*12=48*3\\24x=144$

Dividing both sides by 24

$\frac{24x}{24}=\frac{144}{24}\\x=6$

D. 12 : 15 = x : 20

Product of mean = Product of extreme

$15*x=12*20\\15x=240$

Dividing both sides by 15

$\frac{15x}{15}=\frac{240}{15}\\x=16$
