Question

hi guys please help me in this question ​

Answer 1

Step-by-step explanation:

According to angle sum property of triangle,

sum of all angles of a triangle is 180°

therefore,

(2x - 10) + (3x + 15) + (5x+15) = 180°

10x + 20 = 180

10x = 180 - 20

10x = 160

x = 16

If value of x is 16°

then the angles should be,

2x - 10 ￫ (2 × 16) - 10

32 - 10 = 22°

3x + 15 ￫ (3 × 16) + 15

48 + 15 = 63°

5x + 15 ￫ (5 × 16) + 15

80 + 15 = 95°

Hence, the angles of a triangle are 22°, 63° and 95°
