Question

The three angles of a triangle are x, x+20, x+40 find x also find all the three angles​

Answer 1

Question-

The three angles of a triangle are x, x+20, x+40 find x also find all the three angles​

Answer-

x + x + 20° + x + 40° = 180° (angle sum property of triangle)

3x + 60° = 180°

3x = 120°

x = 40°

The three angles are -

1. x = 40°
2. x + 20° = 60°
3. x + 40° = 80°

Answer 2

The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h. This formula is applicable to all types of triangles, whether it is a scalene triangle, an isosceles triangle or an equilateral triangle.
