Question

Please solve this problem.​

Answer 1

Answer:

Step-by-step explanation:

sin^2 theta + 4 sin^2 theta +4 cos^2 theta=

sin^2 theta+4(sin^2 theta+ cos^2 theta)=sin^2 theta+4=9/2

sin^2 theta=1/2

sin theta= square root(1/2)

theta =45 degrees

tan 45=1

check

5(1/2)+4(1/2)=9/2

I hope its help you.
