Find the value of b that will make the equation sin 62°= cos b true when 0°

Hello from MrBillDoesMath!

b = 28 degrees

Discussion:

In general,

sin (90 - @) = cos(@)

Set 90 [email protected] = 62  => @ = 28 so

sin (90-28) = sin(62) = cos(28)    => b = 28

Thank you,

MrB

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
