Find the c

15 points will name brainlist

c = 13

Step-by-step explanation:

First we use the Pythagorean Theorem to find the hypotenuse.

a^2 + b^2 = c^2

Plug in the known numbers.

5^2 + 12^2 = c^2

Solve

25 + 144 = c^2

169 = c^2

13 = c

Checking the equation.

5^2 + 12^2 = 13^2

25 + 144 = 169

169 = 169

The Equation is true!

this doesn't make sense lol

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
