Hey :)
x= -12
Use the distributive property to multiply −4 by 2x+13
−8x−52=3x+80
Subtract 3x from both sides
−8x−52−3x=80
Combine −8x and −3x to get −11x
−11x−52=80
Add 52 to both sides
−11x=80+52
Add 80 and 52 to get 132
−11x=132
Divide both sides by −11
x= 132/-11
Divide 132 by −11 to get −12
x=−12
Hope this helps :)
Sine 40 = 5 / hypotenuse
0.64279 = 5 / hypotenuse
hypotenuse = 5 / 0.64279
