Answer:
x^2+x+1
Step-by-step explanation:
(x-2)+(x^2+3)=x-2+x^2+3=x^2+x-2+3=x^2+x+1
Answer:
Step-by-step explanation:
one angle is 80
let other angle be 'x'
then third angle will also be equal to x. (given)
using angle sum property,
x + x + 80 = 180. (1)
2x=100
x=50. (2)
therefore all angles are 80,50,50

Answer:
6.28 cm
Step-by-step explanation:
Given,
Diameter = 2 cm
pi = 3.14
To find : Circumference ( circle ) = ?
Radius ( r )
= Diameter / 2
= 2 / 2
= 1 cm
Formula : -
Circumference ( circle ) = 2 pi r
2 pi 4
= 2 × 3.14 × 1
= 6.28 cm
