Answer:
x = 6.5cm
Step-by-step explanation
Assuming that you know the abbreviation SOH CAH TOA, you can solve this easily
What we need to find is x, which is the adjacent (A) side. The other value given is the hypotenuse (H), 13cm. We will see that given A and H, we can use cosine .
cos(60) = x / 13 (remember: cos(angle) = A / H)
Multiply 13 to the other side to get x by itself,
13cos(60) = x
x = 13cos(60)
= 6.5
Hope this helps!
