Step-by-step explanation:
Answer:
x = 11.7
Step-by-step explanation:
sin of an angle is opposite/hypotenuse
sin 38 = x/19
x = 19 sin 38
x = 11.7
You need to memorize the definitions of all the trig functions and then this type of problem will be easy for you.
The first thing you should do is verify that the ordered pairs satisfy equality. If so, then that pair ordered belongs to the line. Let us begin:
3x-4y = 9
(-1.3)
3 (-1) -4 (3) = 9
-3-12 = 9
-15 = 9 (Does not belong)
(2/3, -7 / 4)
3 (2/3) -4 (-7/4) = 9
6 + 28 = 9
34 = 9 (Does not belong)
(-5, -6)
3 (-5) -4 (-6) = 9
-15 + 24 = 9
9 = 9 (Yes, it belongs)
(1, -3 / 2)
3 (1) -4 (-3/2) = 9
3 + 6 = 9
9 = 9 (Yes, it belongs)
answer
ordered pairs are
(-5, -6)
(1, -3 / 2)
