Work out the size of each of the angles. thank you!

Step-by-step explanation:

a=360°-300°=60°{reflex angle}

b=180°-40°=140°{straight angle}

hope it helps.

Step-by-step explanation:

For a

a + 300° = 360° { being complete turn }

a = 360° - 300°

a = 60°

For b

b + 40° = 180° { being linear pair }

b = 180° - 40°

b = 140°

answer: options?

step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
