(3 cos x-4 sin x)+(3sin x+4 cos x)=5
(3cos x+4cos x)+(-4sin x+3 sin x)=5
7 cos x-sin x=5
7cos x=5+sin x
(7 cos x)²=(5+sinx)²
49 cos²x=25+10 sinx+sin²x
49(1-sin²x)=25+10 sinx+sin²x
49-49sin²x=25+10sinx+sin²x
50 sin² x+10sinx-24=0
Sin x=[-10⁺₋√(100+4800)]/100=(-10⁺₋70)/100
We have two possible solutions:
sinx =(-10-70)/100=-0.8
x=sin⁻¹ (-0.8)=-53.13º (360º-53.13º=306.87)
sinx=(-10+70)/100=0.6
x=sin⁻¹ 0.6=36.87º
The solutions when 0≤x≤360º are: 36.87º and 306.87º.
Giant spider crab are further from the surface the wolf because -800 is farther down than -300 let say the surface is 0 going down is negative you react -300 before -800
Answer:
x>7
Step-by-step explanation:
x-3>4
Add 3 to both sides
x>7

One die can show the values 1-6, while the other die can only show 0 or 6. So the possible totals are 1 through 6 plus 0 and 1 through 6 plus 6. Written out, one-by-one, this gives:
1+0 = 1
2+0 = 2
3+0 = 3
4+0 = 4
5+0 = 5
6+0 = 6
1+6 = 7
2+6 = 8
3+6 = 9
4+6 = 10
5+6 = 11
6+6 = 12</span>
