In ques 6 (d) is correct

hope it's help

Answer 2

Step-by-step explanation:

question 6= (d) an acute angled triangle.

solution = ratio of angles= 2:3:4

let the angles are 2x, 3x, and 4x

2x+3x+4x=180 degree

9x=180 degree

x=180/9

x=20

2x=40

3x=60

4x=80

thus, all angles are less than 90 degrees therefore the triangle is acute angled triangle.

question5=(b) x-1/x
