La of sine:
sinC/c = sinB/b==> sin 37°/8 = sin B/12 ==> sin B = 0.903
arcsinB or sin⁻¹ B = 64.5°, & sin (B°) = sin (180° - B°), then
sin(64.5) = sin(180°-64.5°) ==> B = 64.5° or 115.5°
D. 118 would be the answer
Answer:
Trigonometric ratio is the special measurements of a right triangle. There are three basic trigonometric ratios which are sine , cosine , and tangent.
Step-by-step explanation:
What is sine? The sine of an angle x is the length of the opposite side.
What is cosine? The cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse.
What is tangent? The tangent of an angle is the length of the opposite side
Tangent and sine are very closely related and easily mixed up. Be carful with your calculations for the most accurate answer.
Answer:
So these two equation can be related by identity 
Step-by-step explanation:
We have given equation 
And
We know the algebraic identity 
From this identity
can be written as (x+1) (x-1)
And using same identity 
can be written as 
So these two equation can be related by identity
I=20 amps.
By the way, did you know that this is Ohm's Law?
