I will try my best to answer this, but it will be difficult to determine which angles and distances are where since you did not provide the picture. 

You can use the tangent of the 57 degree angle to find your answer. 
tan=opposite/adjacent 
tan(57 degrees)=1.3/X
X=1.3/tan(57 degrees)

Explain how to perform a​ two-sample z-test for the difference between two population means using independent samples with known
iren2701 [21]

Answer:

The steps 1-7 have been explained

Step-by-step explanation:

The steps are;

1) We will verify that the population standard deviations are known and that the population is normally distributed which means the sample size must be a minimum of 30.

2) We will state the null and alternative hypothesis

3) We will determine the critical values from the relevant tables

4) From the critical values gotten, we will determine it's corresponding region where it can be rejected.

5)We will calculate the value of the test statistic from the formula;

z = [(x1' - x2') - (μ1 - μ2)]/√[((σ1)²/n1) + ((σ2)²/n2)]

6) If the value of the test statistic gotten from step 5 above falls in the region of rejection noted in step 4,then we will reject the null hypothesis

7) After rejection of the null hypothesis, we will now give a decision/conclusion on the claim.

If XYZ ~ EDF, the measure of angle F is _____ a0°.
hoa [83]

Answer:

63° (same as Z)

Step-by-step explanation:

The question indicates that ΔXYZ is similar to ΔEDF.

By definition, when we indicate that triangle XYZ is similar to the triangle EDF, the order of the letters is important and match the congruent angles.

So, ∠X = ∠E, ∠Y = ∠D and ∠Z = ∠F

It's hard to see because the angles are quite similar in opening (56°, 63° and 61°), and the drawing doesn't seems to be to scale.

But according to the naming convention: ∠Z = ∠F

Since ∠Z = 63°, ∠F = 63°
