<h3>
Answer: 139.5</h3>
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(55) = 80/x
x*cos(55) = 80
x = 80/cos(55)
x = 139.4757 approximately
x = 139.5
Answer:
60 minutes.
Step-by-step explanation:
Distance = Rate × Time
14 miles = 14mph × ?
Hence, time = 14 miles ÷ 14 mph = 1 hour
1 hour = 60 minutes.
He rode his bike for 60 minutes.
Answer:
d = 90°
e = 41°
f = 139°
Step-by-step explanation:
d + 90° = 180° (Angles in linear pair)
-> d = 180° - 90°
-> d = 90°
e = 41° (vertical angles)
f + 41° = 180° (Angles in linear pair)
-> f = 180° - 41°
-> f = 139°
It looks like a “^” because of the negative while it starts at y = -2
