There would be only one possible triangle. All you can do is extend sides BA and CD until they meet since the angles don’t change. :)

Only one !!

As angles are fixed you can just extend the line and so only one triangle is possible !!

300; Since EF is the only segment not included in FHE, just subtract the 60 degrees there from 360 to get the sum of the rest of the circle

360-60 = 300

Hopefully this is right, i'm a little rusty on geometry

A mechanical engineer wishes to compare strength properties of steel beams with similar beams made with a particular alloy. The
Annette [7]

Answer:

50

Step-by-step explanation:

Level of significance, a = 0.01

Type II error probability, b =0.05

From the z-table:

the critical value at 1% level of significance, Zα = Z0.01 = 2.33

the critical value at 5% probability, Zβ = Z0.05 = 1.645

The critical value of z can be obtained from the standard normal table using the desired level of significance and the tail of test.  

The critical value tells the number of standards deviations away is the result from the mean.

Probability of type I error denoted by  a

Probability of type II error denoted by b.

Type I error is to falsely infer the existence of something that is not there, while a type II error is to falsely infer the absence of something that is.

From the given information,

a=0.01, b=0.05, o1 = o2 =0.05, Dο = 0, D' = 0.04

The sample size is calculated as,

n = ( o^2 + o2^2) * (Za +Zb)^2 /( (D' - D0)^2)

= (0.05^2 +0.05^2)*(2.33 + 1.645)^2 / (0.04 - 0)^2

= 49.38

which is 50 [Rounded to next integer]

Kelly is in a hot air balloon that has just taken off and is now floating 7 meters above its launching point. Denise is standing
irina1246 [14]

Answer:

9.9 meters

Step-by-step explanation:

Given that the distance between Kelly and launching point was 7m and also the distance between launching point and Dennis was also 7m, to calculate for the distance between Kelly and denise is done by applying the formula used for calculating the hypotenuse in a right angle triangle (the shape that was created)

PICTURE ATTACHED IS A DETAILED STEP BY STEP PROCESS OF HOW 9.9m WAS GOTTEN.
