Given: a ∥ b and ∠1 ≅ ∠3
gayaneshka [121]

Answer:

∠1 ≅ ∠2

Step-by-step explanation:

As shown in the figure:

We need to prove e ∥ f using the congruent angle.

So, check the options:

A) ∠2 ≅ ∠4 ⇒ (Wrong)

B) ∠1 ≅ ∠2 ⇒ (True) because a ∥ b (Given)

C) ∠2 ≅ ∠3 ⇒ It is required to prove that to prove e ∥ f , it can't be used.

D) ∠1 ≅ ∠4 ⇒  (Wrong)

The complete sentence will be:

We see that <u>∠1 ≅ ∠2</u> by the alternate exterior angles theorem.

Therefore, angle 2 is congruent to angle 3 by the transitive property.

Im struggling a bit can someone help me? Must show all work.
mart [117]
For this, it's like finding a partial volume. Altogether, there will be 10 inches of sand, because 4+6 is 10. Because it is in inches, we have to convert it to feet. 10 inches in feet is 10/12 feet, or about .833. This is then used for the volume formula instead of the 1 foot height. So, the equation is 6 times 4 times 10/12. This comes out to be 20. 
Hope this helps :)

Using a 5% level of significance and a sample size of 25, what is the critical t value for a null hypothesis, H0: µ ≤ 100? Selec
nadezda [96]

Answer:

D. 2.064

Step-by-step explanation:

Number of sample (n) = 25, degree of freedom = n - 1 = 25 - 1 = 24, significance level = 0.05

The critical t value corresponding to 24 degrees of freedom and 0.05 significance level is 2.064

(Algebra II) Extra points!!Determine whether y varies directly with x
ludmilkaskok [199]

Answer:

  • k = 1.6
  • y = 1.6x

Step-by-step explanation:

If the variation is proportional dividing the y-value by the x-value will give the same result for all table entries. That quotient is the constant of variation (k).

Here 6.4/4 = 11.2/7 = 16/10 = 20.8/13 = 1.6

The value of y varies directly as x, and the constant of variation is 1.6. The equation is ...

  y = 1.6x
