Question

If in triangle abc ab=9cm bc =40 cm and ac =41 cm then the triangle abc is a/an
Acute angled triangle
Right triangle
Obtuse angles triangle
Isosceles triangle

Answer 1

Answer:

I guess it's an acute angled triangle

Step-by-step explanation:

let the angles be x

by taking the cm:9x,41x and 40x

9x+40x+41x=180 degree (angle sum property of triangle)

90x=180 degree

x=180/90

x=2 degree

By substituting the values

18

80

82 degrees

acute angle is less than 90 degrees.

so it is an acute angle triangle.
