Which of the following statements must be true about this diagram? Check

Dmitry_Shevchenko [17]

Hey There!!

By looking at the diagram:

m3 = 180-m4

sum of the angles = m1 + m2 + m3 = 180 degrees

substituting the value of m3:

m1 + m2 + ( 180 - m4 ) = 180

m4= 180 - m3

m1 + m2 + (180 - m4) - (180-m4) = 180 - (180-m4)

Hence:

m1 + m2 = m4

so the right answers after concluding from the above calculations is:

A. m1 + m2 = m4

C.m4 is greater than m2

D. m4 is greater than m1

The length of a rectangle is 3 centimeters less than five times its width. Its area is 14 square centimeters. Find the dimension

katrin [286]

Step-by-step explanation:

Let breadth =x

Length=5x-3

As we know that in a rectangle

$\boxed{\sf Area=lb}$

Substitute the values

${:}\hookrightarrow\sf x (5x-3)=14$

${:}\hookrightarrow\sf 5x^2-3x=14$

${:}\hookrightarrow\sf 5x^2-3x-14=0$

${:}\hookrightarrow\sf 5x^2-10x+7x-14=0$

${:}\hookrightarrow\sf 5x (x-2)+7 (x-2)=0$

${:}\hookrightarrow\sf (x-2)(5x+7)=0$

${:}\hookrightarrow\sf x-2=0\quad or\quad 5x+7=0$

${:}\hookrightarrow\sf x=2\:or\:x=\dfrac {-7}{5}$

Ignore negative value

${:}\hookrightarrow\sf Breadth =2cm$

${:}\hookrightarrow\sf Length=5 (2)-3=10-3=7cm$
