So there’s no actual question because you didn’t attach anything
We have that
<span>sin x=2/9
we know that
sin</span>² x+cos² x=1---------> cos² x=1-sin² x-----> cos² x=1-(2/9)²
cos² x=1-(4/81)------> (81-4)/81-----> 77/81
cos x=√(77/81)
Sin 2x = 2 sin x cos x-------> 2*(2/9)*(√(77/81))----> (4/81)*√77---> 0.43
Sin 2x=0.43
so
cos² 2x=1-sin² 2x---------> 1-[0.43]²-----> 1-[0.1878]----> 0.81
cos² 2x=0.81-----------> cos 2x=0.9
tan 2x=sin 2x/cos 2x--------> tan 2x=0.43/0.9---------> tan 2x=0.48
the answers are
sin 2x=0.43
cos 2x=0.9
tan 2x=0.48
The standard form: Ax + By = C.
The point-slope form:
7. We have the points (4, -7) and (2, -3). Substitute:
8. We have the points (1, 5) and (-10, -6). Substitute:
Answer:
im not the best in math but I think its 95 since a line segment is 180 degrees and you add tge two number and subtract what you have
hope this hells
