Answer:
Option (3)
Step-by-step explanation:
In a right triangle,
Cosine rule →
Sine rule → 
In the given triangle,
By cosine rule,


Or cos(h°) = z ÷ x
Therefore, Option (3) will be the answer.
Answer:
6s(5k+3)
Step-by-step explanation:
18s+30sk
Factor out 6.
6(3s+5sk)
Consider 3s+5sk. Factor out s.
s(3+5k)
Rewrite the complete factored expression.
6s(5k+3)
The function has a slope : m = - 2 and contains the point ( 8, 12 ).
y = m x + b
12 = ( - 2 ) * 8 + b
12 = - 16 + b
b = 12 + 16
b = 28
The slope-intercept form of the function is:
y = - 2 x + 28
Step-by-step explanation:

here ( + ) × ( - ) = ( - )
