What about them????....<span>If two angles of a triangle have measures equal to the measures of two angles of another triangle, then the triangles are <span>similar"</span></span>
So to do this, we take any 2 coordinate points and subtract them to find the slope. For this one i'll go ahead and and take (4,6) and (-2,1), then we set them up. Subtract the X coordinates from each other and the Y's from each other.
4-(-2) change the two negatives to 4+2=6
6-1=5
So 6/5 is the slope, now lets simplify to get 6/5.
Your equation is y=6/5x+3
-Seth.
P.S. It may be y=6/5x+2.5 or something, i cant tell exactly where it goes through the y intercept.
We know that
2π/3 radians-------> convert to degrees-----> 2*180/3---> 120°
120°=90°+30°
Part a) Find <span>sin(2π/3)
</span>sin(2π/3)=sin (90°+30°)
we know that
sin (A+B)=sin A*cos B+cos A*sin B
so
sin (90°+30°)=sin 90*cos 30+cos 90*sin 30
sin 90=1
cos 30=√3/2
cos 90=0
sin 30=1/2
sin (90°+30°)=1*√3/2+0*1/2-----> √3/2
the answer part a) is
sin(2π/3)=√3/2
Part b) Find cos (2π/3)
cos (2π/3)=cos (90°+30°)
we know that
cos (A+B)=cos A*cos B-sin A*sin B
so
cos (90°+30°)=cos 90*cos 30-sin 90*sin 30
sin 90=1
cos 30=√3/2
cos 90=0
sin 30=1/2
cos (90°+30°)=0*√3/2-1*1/2----> -1/2
the answer part b) is
cos (2π/3)=-1/2
