Question

can u answer this?? its from intorduction to trignometry!

Answer 1

Answer:

thetha = 45 degrees

Step-by-step explanation:

Note-I will use a instead of thetha.

$2 { \sin( \alpha ) }^{2} = 1 \\ { \sin( \alpha ) }^{2} = \frac{1}{2 } \\ \sin( \alpha ) = \frac{1}{ \sqrt{2} } \\ \alpha = 45$

Hope it helps you mate.

Plz mark branliest.

Answer 2

Answer:

Formula used :

Sin^2theta +cos^2 theta =1

Step-by-step explanation:

2sin^2theta =sin^2theta +cos^2theta

2 =sin^2theta /sin^2theta+cos ^2theta /sin^2theta

2 =1 +tan ^2theta

Tan^2theta =1

Tan theta =1

Theta =45
