Note: This is the answer if you are talking about a triangle because you didn't specify that.

A=30°

I'm going to assume this is a triangle so if I'm wrong tell me in the comments. If it is a triangle all the angles should add up to 180 degrees. We already know that one is 90 so the other two angles have to add up to 90 (since 90+90=180). C is twice as much as A. So 1/3 of 90 is A and 2/3 of 90 is C. <em>A would be 30°</em>. In summary A=30° B=90° C=60°. Hopefully I understood your question correctly and this helped you. Also sorry it took a while to answer.

A laptop computer is purchased for $2000. After each year, the resale value decreases by 25%. What will the resale value be afte
wel

Answer:

2000? ... assume $2000

Resale Value = $2000*(1 - 0.25)t/yr

where: t = number of year after purchase

at t = 3 yr

Resale Value = $2000*(1 - 0.25)3 = $843.75

checking: at t = 0 $2000 (purchase price)

at t = 1 yr $2000 - 0.25*$2000 = $2000 - $500 = $1500

at t = 2 yr $1500 - 0.25*$1500 = $1500 - $375 = $1125

at t = 3 yr $1125 - 0.25*$1125 = $1125 - $281.25 = $843.75

Solve 4 cos2x-3 = 0 for all real values of x.
vichka [17]

4 cos² x - 3 = 0

4 cos² x = 3

cos² x = 3/4

cos x = ±(√3)/2

Fixing the squared cosine doesn't discriminate among quadrants.  There's one in every quadrant

cos x = ± cos(π/6)

Let's do plus first.  In general, cos x = cos a has solutions x = ±a + 2πk integer k

cos x = cos(π/6)

x = ±π/6 + 2πk

Minus next.

cos x = -cos(π/6)

cos x = cos(π - π/6)

cos x = cos(5π/6)

x = ±5π/6 + 2πk

We'll write all our solutions as

x = { -5π/6, -π/6, π/6, 5π/6 } + 2πk integer k
