Answer 1

Step-by-step explanation:

sum of angles of triangles =180°

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

6x + 30 = 180°

6x = 180° - 30°

6x = 150 °

x = 150/ 6

x = 25 ----- (1)

substitute value of "x" to (***)

(2x + 15 ) = 2 * 25 +15 = 50+15 = 65

(x + 10 ) = 25 + 10 = 35

(3x + 5) = 3*25 + 5 = 75+5 = 80

substituting values in eq (***)

65 + 35 + 80 = 180

180 = 180
