Answer:
24
Step-by-step explanation:
Multiple (4)(2)= 8
-3(8) =24
For this case we can use the law of the sine to solve the problem.
We have then:

From here, we clear the value of x.
We have then:

Rewriting we have:
Answer:
The angle R is given by:
x = 68 degrees
option B
Answer:
see explanation
Step-by-step explanation:
Under a clockwise rotation about the origin of 90°
a point (x, y ) → (y, - x ) , then
R(2, - 1 ) → R'(- 1, - 2 )
S(4, 0 ) → (0, - 4 )
T(1, 3 ) → T'(3, - 1 )
