Question

the sides of a right angled triangle are x-1,x and x+1.Find the value of x and hence the sides of the triangle​

Answer 1

Answer:

Let

A=x-1

B=x

C=x+1

Measurements all angle of triangle is 180°

A+B+C=180°

x-1 + x + x+1=180°

3x = 180°

x= 60°

Measurements of Angle

A=59°

B=60°

C=61°

Answer 2

Step-by-step explanation:

given,

the sides of right angled triangle are x-1 and x and x+1

x = 90 ( given it is right angled triangle)

so,

90 +( x-1) +( x+1 )= 180 (sum of the angles of a triangle )

90+2x = 180

2x = 180 -90

2x = 90

x= 90 /2

x = 45

x+1 = 45 +1 = 46

x-1 = 45 - 1 = 44

therefore the angles are 46,44,90
