Answer:
Step-by-step explanation:
sin²β + sin²β×tan²β = tan²β 
sin²β( 1 + tan²β ) = tan²β 
~~~~~~~~~~~~~~~~ 
<u><em>sin²β + cos²β = 1  </em></u>
<u><em /></u> +
 +  =
 =  ⇒ tan²β + 1 = sec²β ⇔ 1 + tan²β = sec²β
 ⇒ tan²β + 1 = sec²β ⇔ 1 + tan²β = sec²β 
~~~~~~~~~~~~~~ 
1 + tan²β =  
 
L.H. = sin²β (  ) = tan²β
 ) = tan²β 
R.H. = tan²β 
 
        
             
        
        
        
Answer:
12
Step-by-step explanation:
The formula for the tangent of an angle is the length of the opposite side divided by the length of the adjacent side. Therefore, the tangent of angle x is 420/2000=0.21. Taking the arctangent of that to get the angle, you get about 12 degrees. Hope this helps!

Answer:
8.0
Step-by-step explanation:
Since we are trying to find the nearest tenth decimal place, we look at the hundredths place to figure it out. Since it is ≥5, we round up.
