Answer:

2.96

Step-by-step explanation:

The cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse. In this case:

$\cos 65=\dfrac{x}{7}$

$x=7\cdot \cos 65\approx 2.96$

Hope this helps!

Answer:

7) a = 60; b = 100

8) c = 20

9) d = 45

Step-by-step explanation:

b + 80 = 180

b = 100

5c + 4c = 180

9c = 180

c = 20
