Answer:

x = 13

Step-by-step explanation:

Since AD is a straight line, then the 3 angles at C sum to 180° , thus

∠ BCE = 180° - (90 + 64)° = 180° - 154° = 26°

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ ABE is an exterior angle of the triangle, thus

3x = x + 26 ( subtract x from both sides )

2x = 26 ( divide both sides by 2 )

x = 13

Caleb spent 34.95 on 5 pounds of coffee. how much was the coffee per pound?

horsena [70]

It would be $6.99. All you have to do is divide the total (34.95) by pounds of coffee (5). 34.95 / 5 will give you 6.99! You can check this by doing 6.99 * 5, which would again give you 34.95. Contact me if you need any more help. :^)

What is the radius of a circle in which a 30° arc is 2π inches long?

son4ous [18]

First of all, let's recall that the full circumference is

$C = 2\pi r$

Now, since 30 is one twelfth of 360, a 30° arc will be one twelfth of the whole circumference. So, if you call the arc length A, you have

$A = \cfrac{C}{12} = \cfrac{2 \pi r}{12} = \cfrac{\pi r}{6}$

Since we know the arc length, we can build and solve the following equation:

$\cfrac{\pi r}{6} = 2\pi \iff \cfrac{r}{6} = 2 \iff r = 12$
