Answer: 
Step-by-step explanation:
By the geometric mean theorem,

So, by the Pythagorean theorem,

A)
sinA = 8√3 / 16 = √3 / 2
answer is B
√3 / 2
B) It's 30 60 90 right triangle
so <B is 30
answer is A
m<B = 30
Step-by-step explanation:
Take n common
n(n²+2n-15)=0
now factorise the quadratic one as n when goes to RHS it becomes zero
n²-3n+5n-15=0
n(n-3)+5(n-3)=0
n=3,-5
