Question

if three angle of a triangles are (2x-5) (5x+5) and (3x+50) then the value of x is

Answer 1

Answer:

Given the angles of the Triangle are

2x,3x,5x

Hence, 2x+3x+5x=180o (Interior angle sum is 180o)

⇒10x=180o⇒x=10180o=18o

So, the angles are

2x=2∗18o=36o3x=3∗18o=54o5x=5∗18o=90o

Step-by-step explanation:

We know that the sum of the angles of a triangle is 180o. 

∴2xo+3xo+5o+4xo−14o=180o⇒9xo−9o=180o

⇒9xo=180o+9o=189o

⇒x=9o189o=21

∴2xo=(2×21)o=42o,(3x+5)o=[(3×21+5)]o=68o

(4x−14)o=[(4×21)−14]o=70o

Hence, the angles of the triangle are 24o, 68o and 70o.
