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

sin 25

Given: cos α = 4/5, sin β= 4/5, and α and β are both in quadrant 1. find sin (α+β)
mezya [45]
We have the formula (sin x)^2 + (cos x)^2 = 1;
Then, sin α = \sqrt{1-  ( \frac{4}{5}) ^{2} } =  \frac{3}{5} ;
cos β = \sqrt{1- ( \frac{4}{5}) ^{2} } = \frac{3}{5} ;
We apply the formula sin ( α + β ) = sin α x cos β + sin β x cos α = (3/5)x(4/5) + (4/5)x(3/5) = 12/25 + 12/25 = 24/25;
