Answer:  D.  Can't be determined

Step-by-step explanation:

For similarity we need two congruent angle pairs or three similar sides, or two similar sides with an included congruent angle.   We have two right angles, so one congruent pair, not two, not AA.     We only have one pair of sides, no SSS.   We have an angle but not two sides, so no SAS.

Calculate the mass of sodium azide (2NaN3) required to decompose and produce 1.20 moles of nitrogen.
Ad libitum [116K]

Answer:

The answer to your question is:  40.8 g of NaN₃

Step-by-step explanation:

NaN₃ mass = ?

nitrogen = 1.2 moles

Equation

                           2NaN₃      ⇒ 2Na  +  3N2

                          2 moles of NaN₃  -----------------   3 moles of N₂

                           x                          ------------------   1.2 moles of N₂

                          x = (1.2 x 2) / 3

                          x = 2.4/ 3

                         x = 0.8 moles of NaN₃

MW NaN₃ = 23 + 28

                = 51 g

                         51 g of NaN₃ ----------------- 1 mol

                         x                    ----------------- 0.8 mol

                         x = (0.8 x 51) / 1

                        x = 40.8 g of NaN₃

I need help with this question.
ahrayia [7]

Answer:

59

Step-by-step explanation:

We know that all the angles must add up to 180

so we have

38+2b-20+b-15=180

solve for b

3b+3=180

3b=177

b=59

I need help with this asap please !! find the value of X
elena-s [515]

Answer:

x = 11

Step-by-step explanation:

By using angle bisector theorem,

"Bisector of an angle divides the opposite side of the angle into two segments such that they are proportional to the other two sides.

\frac{AC}{CD}= \frac{AB}{BD}

\frac{8}{4}=\frac{x+3}{x-4}

8(x - 4) = 4(x + 3)

8x - 32 = 4x + 12

8x - 4x = 32 + 12

4x = 44

x = 11

Therefore, value of x is 11.
