Answer:
270°
Step-by-step explanation:
360/4 = 90
90*3 = 270
270 degree angle that turns through three-fourth of a circle.
8x^2=2+3
8x^2=5
x^2=5/8
x= sqrt(5/8)
-3x-9
divide the equation by -1 so that the -1's are taken from -3x and -9. so the -1 goes on the outside of 3x+9
-1(3x+9)
then divide the equation by 3 since 3x and 9 is divisible by 3.
(-1)(3)(3/3x+9/3)
-3(x+3)
Now we can expand again to check the problem
-3 times x=-3x
-3 times 3=-9
and add
Hope that helps :)
4(x+4) =2x-18
4x+16=2x‐18
4x–2x= –18 –16
2x= – 34
x= –34/2
x= – 17
I hope I helped you^_^
