Top triangle: if the know angle measures are 90 and 55 and there are a total of 180, 90 + 55 + a = 180. This means that angle a = 35°
Bottom triangle: if a is 35, the angle connected to it is 35 because they are vertical angles. The angles of this triangle are 35 + 120 + b = 180. Angle b = 25°
Answer:
56.7 mi/h
Step-by-step explanation:
The formula for average speed is:
Average Speed = 
Thus we have:
Average Speed =
mph
<em>Rounding to the nearest tenth, we have </em>
Average Speed = 56.7 mi/h
Answer:
m = 
Step-by-step explanation:
Given
y = mx + b ( subtract b from both sides )
y - b = mx ( divide both sides by x )
= m
