The answer for this is n(3+2)
Answer:
angle R
Step-by-step explanation:
To solve this we will use cosine rule
Cosine rule
cos(A) =
suppose,
q = 6.25
s = 11.04
r = 13.19
angleQ =
= 30.58
angleR =
= 93.82
angleS =
= 56.63
The answer is C -5/16 is -0.3 which means -5/16 cant be greater than or less than -0.3 so A and D are wrong and -2/3 is less than -5/16 which leaves us with C!
