Let the side is a cm

s=a+a+a/2(a+a+a=180 because perimeter is 180; 3a=180; a=60)s=180/2=90

Area =√(s(s-a)(s-a)(s-a))√(90(90-60)(90-60)(90-60))√(90*30*30*30√30*30*30*30*30=30*30√30=900√30 cm

the greatest no that can be formed is 76432 and the least no.is 23467 so by subtracting we get the difference 52965

In mathematics, arational numberis anynumberthat can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is arational number. ... Moreover, any repeating or terminating decimal represents arational number.

Slope of line AB4-1/4-13/3tan theta= 145°let after rotation the point B reaches to the point C.such that∠CAB=15thus the slope of the line CA betan(45+15)=tan60=√3the coordinates of the point A are (1,1))therefore the equation of the line CA isy-y₁= m(x-x₁)y-1= √3(x-1)

equation of the line in the new position is (1) √3x +y=2√3

4:12 = 9:27by cross multiplication27×4=12×9108=108so yes they are in proportion.

Given,Perimeter of triangle P = 42 cm

Let third side of triangle be x

Then,x + 18 + 10 = 42x = 42 - 28 = 14

Using HERON'S Formulas = P/2 = 42/2 = 21 cm

Area of triangle A= sqrt(s(s - 18)(s - 10)(s - 14))= sqrt(21(21-18)(21-10)(21-14))= sqrt(21*3*11*7)= 21sqrt(11) cm^2

use a² - b² = (a-b) (a+b)19² - 18² = (19-18)(19+18) = 1 × 37 = 37

thank you

1.5x - 2 = 185x = 18 + 25x = 20x = 20/5x = 4Verification5×4 - 2 = 20- 2 = 18

2. y/4 + 1/2 = 5y/4 = 5 -1/2y/4 = 9/2y = (4×9)/2y = 18

verification18/4 + 1/29/2 + 1/210/25

18×2(1/7)=18×(14+1)/7=18×(15/7)=270/7

270/7 is the answer

18-2+5 = 18+3 = 21 is the answer

Space which has an associated family of subsets that constitute a topology. The relationships between members of the space are mathematically analogous to those between points in ordinary two- and three-dimensional space.
