Answer 1

$\star\:\:\bf\large\underline\blue{Question:-}$

• Find the value of ${ \sin }^{2} 50 \degree + { \cos}^{2} 50 \degree$

$\star\:\:\bf\large\underline\blue{Solution:-}$

We know that,

${ \sin }^{2} \theta + { \cos }^{2} \theta = 1$

$\bf\underline\blue{Therefore,}$

${ \sin }^{2} 50 \degree + { \cos}^{2} 50 \degree$

$= 1$

$\star\:\:\bf\large\underline\blue{Answer:-}$

• Answer for the problem is 1.

Answer 2

Answer:

answer for the given problem is 1

Step-by-step explanation:

we know that

the first trigonometric identity is

sin² A + cos² A= 1 ,

Here A is an acute angle

0°<A<90°

sin² 50° + cos² 50°= 1
