Answer» Step-by-step explanation: Polymers are all created by the process of polymerization wherein their constituent elements called monomers, are reacted together to form polymer chains i.e 3-dimensional NETWORKS forming the polymer bonds. The TYPE of polymerization mechanism USED depends on the type of functional groups attached to the REACTANTS. In BIOLOGICAL contexts, almost all macromolecules are either completely polymeric or are made up of large polymeric chains.

16.

The larger supplementary angle is 30 degree more than the smaller angle . Find the two angles

Answer»

ANSWER:

let smaller ANGLE be X i.e s=x

the larger angle is 30+x i.e l=30+x

we KNOW SUPPLEMENTARY angles add to give 180 so

l+s=180

30+x+x=180

30+2x=180

2x=150

x=75

so small angle 75 degrees while larger angle is 105 degrees

Answer» Answer: Length = 43.37cm Width =3.32cm Step-by-step explanation: A = LB L = x A =LB A = 144cm² Bx = 144 ⇒⇒eq. i Also, PERIMETER = 2L + 2B = 2x + 2B 50cm = 2x + 2B ⇒⇒eq.ii Solving eq.i and eq.ii, 144 = Bx 50 = 2B + 2x From (i., x= 144÷B Substituting into (ii. 50 = 2B +2(144÷B) Multiply THRU by B 50B = 2B² +144 2B² - 50B +144 =0 SOLVE the quadratic B = 3.32 or 21.68 x = 144÷3.32 or 144÷21.68 x = 43.37 or 6.64 ∴∴ The length x = 43.37cm and the width is 3.32cm Since x=43.37 and B=3.32 solve the question best.

A rectangle of area 144 cm square has its length equal to x cm to write down its breath in terms of x given that perimeter is 50 to write down the equation in text to solve to determine the dimension of the rectangle how to determine this?

Answer»

Answer:

Length = 43.37cm

Width =3.32cm

Step-by-step explanation:

A = LB

L = x

A =LB

A = 144cm²

Bx = 144 ⇒⇒eq. i

Also,

PERIMETER = 2L + 2B

= 2x + 2B

50cm = 2x + 2B ⇒⇒eq.ii

Solving eq.i and eq.ii,

144 = Bx

50 = 2B + 2x

From (i., x= 144÷B

Substituting into (ii.

50 = 2B +2(144÷B)

Multiply THRU by B

50B = 2B² +144

2B² - 50B +144 =0

SOLVE the quadratic

B = 3.32 or 21.68

x = 144÷3.32 or 144÷21.68

x = 43.37 or 6.64

∴∴ The length x = 43.37cm and the width is 3.32cm

Since x=43.37 and B=3.32 solve the question best. Thank you!!

Answer:

LET the angles be 2x , 3x , 4x

Sum of the angles WOULD be 180°

2x + 3x + 4x= 180°

9x= 180°

x=20°

Smaller ANGLE, 2x= 2*20°
