If you know the measure of one of the 8 angles, you can find the measure of all of the others. Try it. The measure of <1 = 12

MariettaO [177]

Answer:

$\angle 2 =60$

$\angle 3 = 60$

$\angle 4 = 120$

$\angle 5 = 120$

$\angle 6 = 60$

$\angle 7 = 60$

$\angle 8 = 120$

Step-by-step explanation:

Given

$\angle 1 = 120^\circ$

See attachment

Required

Determine the other angles

$\angle 1$ and $\angle 2$ are on a straight line.

So;

$\angle 1 + \angle 2 =180$

Make $\angle 2$ the subject

$\angle 2 =180 - \angle 1$

$\angle 2 =180 - 120$

$\angle 2 =60$

$\angle 1$ , $\angle 4$ , $\angle 5$ and $\angle 8$ are corresponding angles.

So;

$\angle 4 =\angle 1 = 120$

$\angle 5 =\angle 1 = 120$

$\angle 8 =\angle 1 = 120$

Similarly; $\angle 2$ , $\angle 3$ , $\angle 6$ and $\angle 7$ are corresponding angles.

So;

$\angle 3 =\angle 2 = 60$

$\angle 6 =\angle 2 = 60$

$\angle 7 =\angle 2 = 60$

Football Air Pressure During the National Football League’s 2014 AFC championship game, officials measured the air pressure on 1

lord [1]

Answer:

The null hypothesis is: $H_0 :\mu = 12.5$

The alternative hypothesis is: $H_a :\mu$

Step-by-step explanation:

Consider the provided information.

It is given that the average air pressure in footballs used by the Patriots was significantly less than the allowable limit of 12.5 psi.

The null hypothesis indicates that there is no substantial difference between given populations, due to sampling or experimental error, any observed difference.

Therefore, the null hypothesis is: $H_0 :\mu = 12.5$

The required alternative hypothesis is: $H_a :\mu$

Ian worked 45 hours in a week, earning a total of $1101.60. He worked 35 hours normal time, 8 hours of time and a half and 2 hou

Fofino [41]

Answer:

$21.6/hr

Step-by-step explanation:

Time paid

For 8 hours paid as 1.5, time is 8*1.5=12 hours

Similarly, for double hours, then it is 2*2=4

Given 35 normal hours, the total time will be the sum of 35, 12 and 4 hence 35+12+4=51 hours

Considering the pay of $1101.60 this is equivalent to hourly pay of 1101.60/51=21.6

Therefore, the hourly pay is $21.6 per hour
