Question

Three angles of a triangle are in the ratio of 3:4:5. Find the angle.​

Answer 1

Answer:

3x + 4x + 5x = 180 degrees which means that 12x = 180. divide both sides of this equation by 12 and you get x = 180 / 12 = 15 degrees. this means that the 3x angles is equal to 45 degrees and the 4x angle is equal to 60 degrees and the 5x angle is equal to 75 degrees. 45 + 60 + 75 = 180 degrees so we're good there.

Answer 2

Step-by-step explanation:

just think 3:4:5=3x, 4x, 5x,

= then ,, 3X+4X+5x=180°

= 12X =180°

X=180°/12

x=15°

then ,,,3X=3×15°

= 45°

4X=4×15°

=60°

5X=5×15°

75°

so ,, angle of triangle is 45 °, 60° ,75°
