In ΔKLM, m = 160 cm, ∠M=145° and ∠K=28°. Find the length of l, to the nearest 10th of a centimeter.

Montano1993 [528]

Answer:

34.0 m

Step-by-step explanation:

The total angle sum in a triangle should be 180° hence the missing angle will be given by

180°-145°-28°=7°

Using sine rule

$\frac {m}{sin M}=\frac {l}{sin L}=\frac {k}{sin K}$

By substituting 160 for m, 145° for M and 7° for L then

$\frac {160}{sin 145^{\circ}}=\frac {l}{sin 7^{\circ}}$

Making l the subject then

$l=\frac {160 sin 7^{\circ}}{sin 145^{\circ}}=33.9956345990643m\\l\approx 34.0m$

What's (-5, 3) reflected along x-axis

Anna71 [15]

Whenever you reflect a point over the x axis, the x coordinate stays the same and the y coordinate is negated. In this case, the y coordinate which is 3 will be negated to become -3, and the x coordinate which is -5 will remain the same. Therefore, the new point is (-5,-3).

I hope this helps.

If Susie paid 827 in taxes on gross income of 1748 what percent of her gross pay is being taken out in taxes

maw [93]

Answer:

47.3 % of Susie gross pay is being taken out in taxes .

Step-by-step explanation:

Formula

$Percentage = \frac{Part\value\times 100}{Total\ value}$

If Susie paid 827 in taxes on gross income of 1748 .

Part value = 827

Total value = 1748

Putting all the values in the formula

$Percentage = \frac{827\times 100}{1748}$

$Percentage = \frac{82700}{1748}$

Percentage = 47.3 %

Therefore 47.3 % of Susie gross pay is being taken out in taxes .
