Sin155° = _____ sin25° sin(-25)° -sin25°
patriot [66]

Answer:

sin 25

Step-by-step explanation:

sin(A − B) = sinA cosB − cosA sinB

sin 155

sin( 180 -25)

A = 180  B = 25

sin180 cos25 − cos180 sin25

Sin 180 = 0

cos 180 = -1

0 - (-1) sin 25

Miko and Raj get the same salary. Every month Miko saves
navik [9.2K]

Answer:

Step-by-step explanation:

The salaries are the same. Only the fraction of how much is saved is quite different.

Equation

x ( 9/11 - 7/9) = 1584

Explanation: The salary amount is x. The fractional amounts saved are also given. You have to take the difference because one of the people saves more than the other.

The amount that is more is 1584.

Solution

9/11 = 0.8182

7/9 = 0.7778

9/11 - 7/9 = 0.8182 - 0.7778 = 0.0404

Put that into the equation.

x(0.0404) = 1584                     Divide by 0.0404)

x(0.0404) = 1584/0.0404        

answer:x = 39204
