Answer:

c. 13.9

Step-by-step explanation:

we can work out the third angle

all angles add up to 180

90 + 30 = 120, 180 - 120 = 60

using law of sines

\frac{x}{ \sin(a) }  =  \frac{b}{ \sin(b) }

where sin(a) = 60, b = 30 and sin(b) = 30

\frac{x}{sin(60)}  =  \frac{8}{ \sin(30) }

x =  \frac{8}{sin(30)}  \times  \sin(60)

x = 13.9

Barbie is thinking of a number. twenty less than on third of the number 72. Find Barbie's
notka56 [123]

First find one third of the number 72. We can do this by either dividing 72 by 3, or by multiplying 72 by 1/3. I will divide 72 by 3.

72/3 = 24

We have completed half of the problem; one third of the number 72. Now the number Barbie is thinking of is twenty less than the number we just found, 24.

To solve this problem subtract 20 from one third of the number 72; 24.

24 - 20 = 4

The number that Barbie is thinking of is 4.

Solve the equation <br>8-2x=-8x+14
Marina86 [1]

8 - 2x = -8x + 14      <em>subtract 8 from both sides</em>

-2x = -8x + 6     <em>add 8x to both sides</em>

6x = 6     <em>divide both sides by 6</em>

<h3>x = 1</h3>

SSSSS [86.1K]
Combine  2a^3+5a-7 and 5a^2-6a+12.

Rewrite this so that the second expression is beneath the first:

2a^3+5a-7 
5a^2-6a+12

Combine like terms.  The highest order term is 2a^3:

2a^3+0a^2 +5a-7 
        +5a^2 - 6a+12
----------------------------
2a^3 + 5a^2 - a + 5 (answer)

Note how these terms are in descending order by power of a.
