Question

please give me answer ​

Answer 1

Step-by-step explanation:

largest angle=75 degree

Answer 2

Answer:

the ratio of angles is 3:4:5

so the angles are 3x, 4x, 5x

sum of all angles of triangle is 180

3x + 4x + 5x = 180

12x = 180

x = 15°

the largest angle is 5x = 5 x 15 = 75°

thus the largest angle is 75°
