For number 9 you just have divide the x side by -7 and then that will get y by itself.
30f+24g-6 because you distribute
First of all, we can use the double angle identity to write
The equation becomes
Divide both sides by 3 to get
And finally consider the square root of both terms (don't forget the double sign):
So, the solutions are
If you want x in [0,360], consider the equivalent angle
Answer: 13
Step-by-step explanation:
I used Pythagorean theorem to solve this problem. As DC and AD is 12 and 5, you would do 12²+5²= c². 12²= 144 and 5²= 25. 144+25= 169. It doesn't end there. Do the square root of 169 ---> √169=13.
