SAT Math 1 Question!!!!!!!!!!!!!!!!!!!!

Test Preparation
1

<p>If angle A is an acute angle and sin^2A / Cos^2A = 2.468 , what is the value of tan A? </p>

<p>I have no clue how to solve this, HELP. Is there a calculator method for this? It's painful.</p>

2

<p>wait is that "to the power of" or "angle'?</p>

3

<p>sin squared!</p>

4

<p>SinA/cosA = tanA. That's a trig rule you should remember, it's really helpful! So:</p>

<p>(sin^2A)/(cos^2A) = (sinA/cosA)^2</p>

<p>And</p>

<p>(sin/cos)^2 = tan^2</p>

<p>So</p>

<p>sin^2A / cos^2A = 2.468
tan^2A = 2.468
tanA = rt(2.468)
tanA = 1.57</p>
