Tanya Singla 8 years, 6 months ago

Given: a+b=120

Therefore, b=120-a ---Eqⁿ1

and, a+c=130

Therefore, c=130-a ---Eqⁿ2

Since we know that the sum of angles of a triangle is 180⁰

=> a+b+c=180⁰ ---Eqⁿ3

Putting values of b and c from Eqⁿ1 and Eqⁿ2 in Eqⁿ3

=> a+120⁰-a+130⁰-a = 180⁰

=> 250⁰-a =180⁰

=> -a = 180⁰- 250⁰

=> angle a= 70⁰

Now putting value of angle a in Eqⁿ1 and Eqⁿ2, we get

angle b= 120-70= 50⁰and

angle c= 130-70= 60⁰

Satvik Jain 8 years, 6 months ago

Let ABC be the triangle and D. E and F are midpoints of BC, CA and AB respectively. Recall that the sum of two sides of a triangle is greater than twice the median bisecting the third side, Hence in ΔABD, AD is a median ⇒ AB + AC > 2(AD) Similarly, we get BC + AC > 2CF BC + AB > 2BE On adding the above inequations, we get (AB + AC) + (BC + AC) + (BC + AB )> 2AD + 2CD + 2BE 2(AB + BC + AC) > 2(AD + BE + CF) ∴ AB + BC + AC > AD + BE + CF Hence, we can say that the perimeter of a triangle is greater than the sum of the medians.

Mohit Sharma 8 years, 2 months ago

1) Let x = 0.00323232.......(i)

Multiply equation (i) by 100 on both sides,

100 x = 0.323232.......(ii)

Multiply equation (i) by 10,000 on both sides,

10,000 x = 32.323232.......(iii)

Subtracting equation (ii) from (iii),

10,000 x = 32.323232.......(iii)
-- 100 x = 0.323232.......(ii)
