Sin (Π/2 - theta) = sin(Π/2) * cos(theta) - cos(Π/2) * sin (theta)
and as we know sin(Π/2) =1 , cos(Π/2)=0
so sin(Π/2 - theta) = 1* cos(theta) - 0* sin(theta)= cos(theta)
2nd cos(180+ theta) = cos(180)*cos(theta) - sin(180)* sin(theta)
,,, so , cos(180+theta) = -cos(theta)

good day.

X + 8 = 60 + 94.
This is geometrically correct, now you must solve the algebra portion.
60 + 94 is just 154, which means x + 8 = 154.
What number + 8 = 154? It must be 146.
I’m pretty sure but not so sure I think it is 180
