$\huge \bf༆ Answer ༄$

Conversion from degree to radian ~

$\boxed{ \sf{ \frac{\pi}{180} \times \theta }}$

$\sf \dfrac{\pi}{180 } \times 90$

$\sf \dfrac{\pi}{2} \: \: rad$

Conversion from radians to degree ~

$\boxed{ \sf{ \frac{180}{\pi} \times \theta}}$

$\sf \dfrac{180}{\pi} \times - \dfrac{ \pi}{5}$

$\sf - 36 \degree$

Answer:

1 ) Adjacent angles,

2 ) See solution below

Step-by-step explanation:

Question 1. Provided ∠ 1 and ∠ 1 are near one another, they can be referred to as adjacent ∠s;

Solution; Adjacent angles

Question 2.

Angles 5, and 6 are consecutively near one another, and thus are adjacent angles,

Angles 5 and 9 are supplementary knowing that they lie on a straight angle, so that they can be best named a linear pair, provided there are only two of these angles,

Angles 5 and 8 are opposite to one another so that they are ≅, thus should be names as vertical angles

Solution; 

Angle | Adjacent Angles | Linear Pair | Vertical angles

∠ 5, 6 | Check! | |

∠ 5, 9 | | Check! |

∠ 5, 8 | | | Check!

$\cot^4 A - \cot^2 A = 1\\\\\cot^4 A = 1 + \cot^2 A\\\\\frac{\cos^4 A}{\sin^4 A} = 1 + \frac{\cos^2 A}{\sin^2 A}\\\\\frac{\cos^4 A}{\sin^4 A} = \frac{\sin^2 A}{\sin^2 A}+\frac{\cos^2 A}{\sin^2 A}\\\\\frac{\cos^4 A}{\sin^4 A} = \frac{\sin^2 A+\cos^2 A}{\sin^2 A}\\\\\frac{\cos^4 A}{\sin^4 A} = \frac{1}{\sin^2 A}\\\\\cos^4 A = \frac{\sin^4 A}{\sin^2 A}\\\\\cos^4 A = \sin^2 A\\\\$
