If sin a = - 4/5<br>and cos a &gt; 0, find tan a and sec a.​
Nina [5.8K]

Answer:

tan(a) = -4/3

sec(a) = 5/3

Step-by-step explanation:

sine is opposite over hypotenuse.  so no we have a triangle with a hypotenuse of 5 and an opposite side relative to some angle a of -4.  the hypotenuse is never negative.  

so draw a right triangle, mark one of the non right angles as a then the side opposite to that is -4 and the hypotenuse is 5.  use the pythagorean theorem to find the remaining angle.  The result could be positive or negative, but the questions specifically tells us we want the positive version.

b^2 + -4^2 = 5^2

b = 3

tangent is opposite over adjacent.  for a we know the opposite is 3now so tan(a) = -4/3

Now, secant is 1/cos, so lets find cos(a)

cos is adjacent over hypotenuse, and we jsut found the adjacent is 3.  so cos(a) = 3/5

Now 1/cos(a) = hypotenuse over adjacent so 5/3

How do you find the answer
KengaRu [80]
You need to measure the angles wich means that u use a protractor if the angle is 90 degrees is a straight angle if it is below 90 degrees is acute and if it is above 90 degrees it's obtuse

Please this is due in 52 minutes...

Answer:

Angle S has a measure of 50°

Step-by-step explanation:

When comparing the angles of a triangle, they are written with the matching angles in the same order. (sorry for bad explanation here)

You have ∆ QRS as congruent to ∆ XYZ. This means angle Q is congruent to angle X, angle R is congruent to angle Y, and angle S is congruent to angle Z. <u>As you can see in ∆ XYZ, angle Z is 50°. Therefore, angle S and angle Z are both 50°</u> (but only angle S is an option)
