Answer:
h = 7
Step-by-step explanation:
18 = (h - 1) × 6 × 0.5
simplify:
18 = 3(h - 1)
distribute the 3:
18 = 3h - 3
add 3 to both sides:
3h = 21
divide by 3:
h = 7

The value of cosθ is 
Step-by-step explanation:
It is given that an angle θ with the point (15, −8) on its terminating side.
Here x=adjacent side=15 units and y=opposite side =-8 units,
Using pythagoras theorem,




Cosine is defined as


Therefore the value of cosθ is
