Answer:
x=-2 y= -5
x=-1 y=-3
x=0 y=-1
x=1 y=1
x=2 y=3
x=3 y=5
Step-by-step explanation:
Answer:
Y=60
Step-by-step explanation:
S+Y=90
S=(2*Y)-90
Y+2Y-90=90
3Y=180
Y=60
Plug back into S+Y=90
S+60=90
S=30
Cos Ф = 11/5. Calculate the value of angle Ф:
cos⁻¹(11/15) = 42.83342807°
sin(90-Ф) =sin (90-42.83342807) = sin(47.16657193) = 11/5
So cos Ф = sin(90-Ф) = 11/15
