Question

value of value of sin square 90 degrees Plus cos square 30 degree ​

Answer 1

Answer:

sin²90° + cos² 30°

=

${1}^{2} + {( \frac{ \sqrt{3} }{2}) }^{2} \\ = 1 + \frac{3}{4} \\ = \frac{4 + 3}{4} \\ = \frac{7}{4} .$

this is the answer.

Answer 2

Answer:

Step-by-step explanation:

${sin}^{2} 90 = {(sin90)}^{2} = {1}^{2} = 1 \\ {cos}^{2} 30 = {( cos30)}^{2} = {( \frac{ \sqrt{3} }{2} )}^{2} = \frac{3}{4} \\ \\ 1 + \frac{3}{4} = \frac{7}{4}$
