it is difficult, i will mark u brainiliest pls answer me fast ​

Answer 1

Answer:

50°, 30° and 100°

Step-by-step explanation:

Sum of all angles in a triangle = 180°

$x + \frac{3x}{5} + \frac{3x}{2} + 25 = 180 \\ x + \frac{3x}{5} + \frac{3x}{2} = 155 \\ \frac{10x + 6x + 15x}{10} = 155 \\ \frac{31x}{10} = 155 \\ 31x = 1550 \\ x = 50$

x = 50

Thus, angles are 50°, 30° and 100°

Answer 2

Answer:

50

Step-by-step explanation:

x + 3x/5 + 3x/2 +25 = 180

8x/5 + 3x +50/2 = 180

16x/10 + 15x + 250/10 = 180

31x + 250/10 = 180

31x + 250 = 1800

31x = 1550

x = 1550/31 = 50
