Question

11.
In a triangle three angles are 3x + 5°, 5x - 15°, 4x + 10°, find the angles of triangle.​

Answer 1

Answer:

we know sum of angles are 180 degree

3x+5+5x-15+4x+10=180

12x=180

x=15

the angles are 50,60,70

Answer 2

Step-by-step explanation:

Sum of all angles of the triangle is 180degree

Therefore according to question

3x+5+5x-15+4x+10=180

12x=180+15-10-5

12x=180

x=15

1st angle =15*3+5=50

2nd angle=5*15-15=60

3rd angle=4*15+10=70
