Question

9. If the angles of a triangle are in the ratio 1:4:5. Find the angles.​

Answer 1

Answer:

A parallelogram is a two-dimensional geometrical shape, whose sides are parallel to each other. It is a type of polygon having four sides (also called quadrilateral), where the pair of parallel sides are equal in length. Also, the interior opposite angles of a parallelogram are equal in measure. Sum of adjacent angles of a parallelogram is equal to 180 degrees.

Answer 2

Explaination:

let all the angles be 1x,4x, and 5x .

1x+4x+5x= 180

10x = 180

x= 18

Angles are.

1x = 18

4x = 72

5x =90
