Answer:

3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units

Step-by-step explanation:

we know that

The isosceles trapezoid has :

Two parallel sides not equal in length called its bases  (KL and NM)

Two non-parallel sides equal in length (LM and NK)

so

NK=\sqrt{5}\ units

The perimeter is equal to

P=KL+LM+NM+NK

substitute the values

P=2\sqrt{2}+\sqrt{5}+\sqrt{2}+\sqrt{5}

P=(3\sqrt{2}+2\sqrt{5})\ units

3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units

How to solve this using trigonometry?
Leya [2.2K]
Using SOHCAHTOA and Kenui's height and angle of depression (which is the downward angle from the horizontal ) the answer should be:  

because its the Adjacent and Opposite sides use Tan;  
Tan(6.8) = o/a
tan(6.8) = Distance / 219
tan(6.8)(219 = Distance 
26.114 m 

But because the angle of depression is the downward angle from the horizontal the answer may be Tan(83.2)(219) = 1836.589
the 83.2 coming from 90 degrees - 6.8 degrees 

either way i"m still unsure because I don't see a need for the two angles or Mias involvement, sorry if I'm wrong

Simplify this expression and show all steps:<br> 48m^7/20m^4
Ghella [55]

Answer:

(12/5)m^3

Step-by-step explanation:

It's easier for most of us to write out a fraction / ratio without the " / " symbol:

48m^7

------------

20 m^4

Separate the coefficients from the powers of m:

48     m^7

----- * --------     Now let's reduce each fraction separately:

20      m^4


48/20 = 12/5, and

(m^7) / (m^4) = m^(7-4) = m^3


... so that our final answer is (12/5)m^3.
