Answer:
(1 + √2)/2
Step-by-step explanation:
Assuming the values are in degrees,
sin(45) = sin(π/4)=√2/2
cos(60) = cos(π/3)=1/2
thus
sin(45) + cos(60) = √2/2 + 1/2 = (1 +√2)/2
Answer:
4 equation 4
Step-by-step explanation:
did math in head
-32 divided by 4, which equals -8
Answer:
9-49
a= 2r+ 7
b= 2.5x + 16
c= 3r-2x-8.8
Step-by-step explanation:
Ce = bf = ag = 1/3(432) = d^2
Therefore, the product of c and e = 1/3(432) = 144
