Answer:
Step-by-step explanation:
sec x( cotx + cos x )= csc x+ 1
1/cos x( cosx/ sinx +cosx) = csc x+ 1
1/cosx ( cosx + sinxcosx/sinx) = csc x+ 1
1/cosx( cosx) ( 1+sinx/sinx) = csc x+ 1
1(1/sinx+1) = csc x+ 1
cscx +1= = csc x+ 1
Answer:
4
Step-by-step explanation:
I = PRT
252 = (900)(.07)(T)
252 = (63)(T)
divide 63 from both sides
4 = T
I think its 20 pounds per 17 square feet (simplest form)
Answer:
x=5/2, x=-4/3
Step-by-step explanation:
Let's set the measure of each angle equal to 540 degrees.
4x + 4x + 5x + 2 + 96 + 5x - 8 = 540
Combine like terms.
18x + 90 = 540
Subtract 90 from both sides.
18x = 450
Divide both sides by 18
x = 25
