Goshia [24]3 years ago
4 0

Answer:

A=(n-3)2\ units^2

A=(2n-6)\ units^2

Step-by-step explanation:

we know that

The area of rectangle is equal to

A=LW

where

L is the length of rectangle

W is the width of rectangle

In this problem we have

L=(n-3)\ units\\W=2\ units

substitute

A=(n-3)2\ units^2

Apply distributive property

A=2(n)-2(3)

A=(2n-6)\ units^2

Answer:

\frac{3\sqrt{2} }{2}

Step-by-step explanation:

Given

\frac{\sqrt{2} }{2} + \frac{2}{\sqrt{2} } ← rationalise the denominator by multiplying by \frac{\sqrt{2} }{\sqrt{2} }

= \frac{\sqrt{2} }{2} + ( \frac{2}{\sqrt{2} } × \frac{\sqrt{2} }{\sqrt{2} } )

= \frac{\sqrt{2} }{2} + \frac{2\sqrt{2} }{2}

= \frac{3\sqrt{2} }{2}

Suppose that m∠MKN = 55°. What is m∠MCN?<br> !please no absurd answers!
Elena L [17]

Answer:

angle M and N are right angles

we can draw a line joining M and N  

so we’d have a triangle MNC AND KMN

both MNC AND KMN BECOME ISOSCELES TRIANGLES

so since we have 55 degrees for angle MKN. We have to find the other 2

180-55=125

now divide by 2 to get 62.5 for each of the remaining sides of triangle KMN

now to find the sides of triangle MNC

90-62.5= 27.5

27.5*2= 55

180-55=125=angle C

(sorry, it’s complex)
