Answer:
Okay what do you want to talk about ?
Step-by-step explanation:
Answer:
cos(B) = a/c
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that ...
Cos = Adjacent/Hypotenuse
The leg adjacent to angle B is "a". The hypotenuse is "c", so the desired cosine is ...
cos(B) = adjacent/hypotenuse = a/c
We have to use Pythagorean theorem that says :

The missing length of the triangle is : 36 feet
Answer:
r = 1
Step-by-step explanation:
