Hence, the speed with which the boy is cycling is 15.84km/hr.
Answer:
Step-by-step explanation:
m∠1 = 2x and m∠2 = -3x+235
angle 1 and angle 2 are supplementary angle so they add up to 180°
m∠1 +m∠2 = 180°
2x -3x+235 = 180°
-x = 180-235
x=35
m∠1 = 2x = 2*35 = 70°
m∠2 = -3x+235 = -3*35 +235 = 235-105 = 130°
