Help pls I'm confused

Sorry this took so long, hope this helps

also the "a^2" is meant to mean this " "

Step-by-step explanation:

1) a^2+b^2=c^2

4^2+3^2=c^2

16+9=c^2

25=c^2

=c

5=c

2) a^2+b^2=c^2

15^2+8^2=c^2

225+64=c^2

289=c^2

=c

15=c

3)a^2+b^2=c^2

10^2+50^2=c^2

100+2500=c^2

2600=c^2

=c

50.99≈c

4) a=

a=

a=

a=

a=9

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?
