Answer: x=12

Step-by-step explanation:

we know that sum of a triangle is 180 degrees

one angle is 90 degree

the sum will be 90+(2x+1)+(5x+5)=180

substract 90 from both sides

2x+1+5x+5=180-90

7x+6=90

7x=90-6

divide by 7

x=12

There are exactly 1,944 of the 12-, or 0.5-, cubes inside a rectangular prism.

drek231 [11]

The volume of the rectangular prism is 3359232 cubic centimeters

<h3>How to determine the volume?</h3>

The length of the cube is given as:

Length, l = 12 cm

The volume of a cube is:

$V = l^3$

So, we have:

$V = 12^3$

Evaluate

V = 1728

The volume of 1944 cubes is then calculated as:

Volume = 1728 * 1944

Evaluate

Volume = 3359232

Hence, the volume of the rectangular prism is 3359232 cubic centimeters

Answer:

$x\degree = 75\degree$

Step-by-step explanation:

Property used: <em>An exterior angle of a triangle is equal to the sum of the opposite interior angles.</em>

$= > 62\degree + (x + 13)\degree = 2x\degree \\ \\ = > 62\degree + x\degree + 13\degree = 2x\degree \\ \\ = > 75\degree = 2x\degree - x\degree \\ \\ = > 75\degree = x\degree \\ \\ = > x\degree = 75\degree$

nikklg [1K]

Answer:

- 1.67

Step-by-step explanation:

f(x) = $\frac{3}{7+2}$ - $\sqrt{7-3}$

= $\frac{3}{9}$ - $\sqrt{4}$

= $\frac{1}{3}$ - 2

= - 1 $\frac{2}{3}$

= -1.6666666
