Answer:

\sin \: x -  \cos  x \:  + c

Step-by-step explanation:

\int \frac{cos2x}{ \sqrt{1 - sin2x} } dx \\  \\  =  \int \frac{ {cos}^{2}x -  {sin}^{2}x }  { \sqrt{ {sin}^{2}x +  {cos}^{2}x - 2sinx \: cosx  }  } dx \\  \\ =  \int \frac{ ({cos}x -  {sin}x )({cos}x  +   {sin}x )}  { \sqrt{  {({cos}x -  {sin}x )}^{2}  }  } dx \\  \\ =  \int \frac{ ({cos}x -  {sin}x )({cos}x  +   {sin}x )}  {{  {({cos}x -  {sin}x )} }  } dx \\  \\  =  \int({cos}x  +   {sin}x)dx \\  \\  = \int{cos}x  \: dx +    \int{sin}x \: dx \\  \\  =  \sin \: x -  \cos  x \:  + c

What are the missing angle measures in triangle ABC?
Finger [1]

we know that

In the right triangle ABC

∠A+∠B=90 ------> by complementary angles

so

Step 1

Find the measure of angle B

we know that

tan\  B=\frac{opposite\  side\  angle\  B}{adjacent\  side\  angle\  B}

in this problem

opposite\  side\  angle\  B=7in\\ adjacent\  side\  angle\  B=5in

so

tan\  B=\frac{7}{5} \\ \\ B=arc\ tan\frac{7}{5} \\ \\ B=54.5\ degrees

Step 2

Find the measure of angle A

A+B=90\\ A=90-B\\ A=90-54.5\\ A=35.5\ degrees

therefore

the answer is the option

35.5° and 54.5°
