Answer:

Scalene type of triangle

Please help me on my math homework also please note that the answer in red is wrong. (This is serious)

Angles LNM and MNI are supplementary, so their measures sum to 180°. This means

∡ LNM + ∡ MNI = 180°

∡ LNM = 180° - (19<em>x</em> + 2)°

The sum of the interior angles of any triangle is also 180°, so

∡ LNM + ∡ NML + ∡ MLN = 180°

(180° - (19<em>x</em> + 2))° + (15<em>x</em> - 2)° + (6<em>x</em>)° = 180°

Solve for <em>x</em> (I'll omit the degree symbol):

180 - 19<em>x</em> - 2 + 15<em>x</em> - 2 + 6<em>x</em> = 180

2<em>x</em> - 4 = 0

2<em>x</em> = 4

<em>x</em> = 2

Then ∡ MNI = (15•2 - 12)° = (30 - 12)° = 18°.

jeyben [28]

The best firm for the Appliance manufacturer for the repair work is Firm 2 .

In the question ,

it is given that ,

An appliance manufacturer wants to contract with a repair shop to handle authorized repairs in Indianapolis .

The acceptable range of the repair time is 50 minutes to 90 minutes.

the mean repair time for firm 1 = 74 minutes and standard deviation of 4 minutes .

the mean repair time for firm 2 = 72 minutes and standard deviation of 5.1 minutes .

the range is calculated using the formula

Range = Mean ± Standard Deviation

So , for firm 1 ,

the Range = 74 ± 4

= 74 + 4       and      74 - 4

= 78     and   70

the range for firm 2 is

= 72 ± 5.1

= 72 + 5.1      and      72 - 5.1

= 7.1        and       66.9  

The second company has a lower range and it should be preferred .

Therefore ,  The best firm for the Appliance manufacturer for the repair work is Firm 2 .
