Question

find value of x and all three angles of triangle if angles are (2x-1°) (x+25°) (3x+12°)

Answer 1

By angle sum property of triangle,

2x - 1 + x + 25 + 3x + 12 = 180

=> 6x + 36 = 180

=> 6x = 180 - 36

=> 6x = 144

=> x = 24

First angle = 2 (24) - 1 = 48 - 1 = 47°

Second angle = 24 +25 = 49

Third angle = 3 (24) + 12 = 72 + 12 = 84°

Answer 2

HEYA!!

➡Use angle Sum Property of a Triangle ,

( 2 x - 1 ) + ( x + 25 ) + ( 3x + 12 ) = 180

6x - 1 + 25 + 12 = 180

6x + 36 = 180

6x = 144

x = 144/6

x = 24°


➡Angles are :

✨ ( 2 × 24 - 1 ) = 47°

✨ ( 24 + 25 ) = 49°

✨ ( 3 × 24 + 12 ) = 84°
