Step-by-step explanation:

 { \cos}^{2} 30 \degree+ \sin30 \degree+ { \tan}^{2} 45 \degree=2 \frac{1}{4}  \\   {( \frac{ \sqrt{3} }{2} )}^{2}  +  \frac{1}{2}  +  {( 1) }^{2}  =  \frac{9}{4}  \\ \\    \frac{3}{4}  +  \frac{1}{4}  + 1 =  \frac{9}{4}  \\  \frac{9}{4}  =  \frac{9}{4} \\ L.H.S = R.H.S  \\  \\ \red{\mathfrak{ \large{\underline{{Hope \: It \: Helps \: You}}}}} \\ \blue{\mathfrak{ \large{\underline{{Mark \: Me \: Brainliest}}}}}

Right ques :

cos²30°+sin²30°+tan²45°=2+(1/4)

=> 3/4 + 1/4+1 = 9/4

=> 9/4 = 9/4

LHS = RHS
