<em>The value of CosA is 0.8191</em>

Step-by-step explanation:

Given SinA= 0.5736

We know that SinA^{2} + CosA^{2} = 1

Replacing value of SinA,

(0.5736)^{2} + CosA^{2} = 1

(0.3290) + CosA^{2} = 1

CosA^{2} = 1-0.3290

CosA^{2} = 0.6709

CosA = 0.8191

The value of CosA is 0.8191

What percent is 25 is 12
Ray Of Light [21]

Answer: 48%

Step-by-step explanation:

I believe you meant, what percent of 25 is 12.

In that case, you would do 12/25 which equals 0.48

To convert a decimal into a percent, you would move the decimal point over 2 digits to the right. That would make 0.48 into 48%

So 48% is the answer.

Hope this helps :)

the measure of one acute angle is twice the difference of the measure of the other acute angle and 12
Dmitrij [34]
Is there a picture to find the measure of the acute angle?  Or do you want an equation to solve it? If so than it is: 2b-12=a, where b is the measure of the other acute angle and a is the measure of the acute angle where it is twice the difference of the measurment of the other acute angle and 12.
