Answer:
D
Step-by-step explanation:
tan=adjacent side/opposite side
sin=adjacent side/hypotenuse
cos=opposite side/hypotenuse
knowing this:
cos P=8/17, so a is false
tan Q=8/15, so b is false
sin P=15/17, so c is false
cos Q= 15/17, so only d is true
Answer:
i
Step-by-step explanation:
Answer:
3.5 hours
Step-by-step explanation:
Given: Distance= 26.2 miles
Speed= 12 km/h
First lets convert the unit of speed from kmh to mph.
Remember, 1 mile= 1.609 km
∴ For speed of 12 km/h= 
Speed= 7.45 mph
Next, find time taken by Allan to complete a Marathon.

⇒ Time= 
∴ Time= 3.516 hours ≅ 3.5 h (nearest tenth)
∴ Allan took 3.5 hours to complete marathon.
Answer: x =
Step-by-step explanation:
-3x -2y = 10 Get x alone by add 2y to both sides
+2y +2y
-3x = 10 + 2y Divide both sides by -3
x = -10/3 - 2y/3
