Answer:

Measure of each of the angles:

(x - 25)° = 50°

(2x - 65)° = 85°

3x = 225°

Explanation:

Angle around a point = 360°

Here,

(2x - 65)° + (x - 25)° + 3x° = 360° [angles around a point]

2x - 65 + x - 25 + 3x = 360°

2x + x + 3x - 65 - 25 = 360

6x - 90 = 360

6x = 360 + 90

6x = 450

x = 450/6

x = 75

Then,

x - 25

= (75) - 25

= 50°

(2x - 65)°

= 2(75) - 65

= 85°

3x°

= 3(75)

= 225°

Hope it helps ⚜

Answer:

Explanation:

3x + x - 25 + 2x - 65 = 360 {Full angle or one point angle}

3x +x + 2x - 65 - 25 = 360

Combine like terms,

6x - 90 = 360

Add 60 to both sides,

6x = 360 + 90

6x = 450

Divide both sides by 6

x = 450/6

x = 75

3x = 3*75 = 225°

x - 25 = 75 - 25 = 50°

2x - 65 = 2*75 - 65 = 150 - 65 = 85°
