98³ can be written as (100-2)³
So, we'll use the identity -
(a-b)³= a³-b³-3a²b+3ab²
(100-2)³ = 100³ - 2³ - 3(100)²(2) + 3(100)(2)²
= 1000000 - 8 - 60000 + 1200
= 941192
Answer - 98 ³ = 941192

Given,
Side a=18cm
Side b=10cm
Perimeter=42cm=a+b+c
:. Putting value
42=18+10+c
42=28+c
42-28=c
14=c
Now,
S=(a+b+c)/2
:. Putting value
S=42/2
S=21
Now according to Heron's formula-
Area of a triangle
=√{s(s-a)(s-b)(s-c)}
:. Putting value
=√{21(21-18)(21-10)(21-14)}
=√{21(3)(11)(7)}
=√4851
=21√11cm²

If (X + 2) is a factor of x2 + mx + 14
Put x = -2
x2 + mx + 14 = 0
(-2)2 + m(-2) + 14 = 0
4 - 2m + 14 = 0
-2m + 18 =0
-2m = -18
m = 18/2 = 9

AB = AC
Therefore, ∠B =∠C ( Angles Opposite to equal sides are equal )
∠A+∠B+∠C = 180° (Angle Sum Property)
or, ∠A+50°+50° = 180°
or, ∠A+100° = 180°
or, ∠A = 180°-100°
or, ∠A=80°
Therefore, ∠A=80°

This ΔABC is an isosceles triangle. In this kind of triangle, two of the sides are equal.
So if AB=AC,
Then vertex= angle A and
Base angles= angle B and angle C which are equal.
Let the base angles angle B and angle C be x.
Since the sum of the angles of a triangle=180°,
Therefore,
angle A + angle B + angle C = 180°
= 120° + x+x= 180°
= 120° + 2x= 180°
= 2x = 180°-120°
= 2x = 60°
= x = 60°/2 =30°
Therefore,
Angle A= 120°
Angle B= 30°
Angle C= 30°.
