Find the measure of each angle indicated.

3) B) 90°

4) A) 75°

Step-by-step explanation:

3) interior angles of a triangle =180°

So

40+50+?=180

? =180- 90

? =90

4) same rule

40+65+?=180

? =180 - 105

? = 75

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
