Answer:
x = 40°
Step-by-step explanation:
using the cofunction identity
cos(90 - x) = sin x , so
90 - x = 50 , then
x = 40
that is sin40° = cos50°
Answer:
below
Step-by-step explanation:
the is the procedure above
If it is 63 in across, and each part is equal, the equation so solve this is: 63=3x
So, you take 63=3x and divide each side by 3
63/3=3x/3
Then simplify
21=x
This means each panel is 21 inches wide.
