<u>Trigonometric Ratios </u>
The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios: sine, cosine, tangent, cosecant, secant, and cotangent.
The longest side of the right triangle is called the hypotenuse and the other two sides are the legs.
Choosing any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.
The image shows a right triangle where the angle of 45° has x as the opposite leg, 6 as the adjacent leg, and y as the hypotenuse. The trigonometric ratio that applies here is the cosine ratio, defined as:
Solving for y:
Substituting:
Now use the tangent ratio:
Solving for x:
Substituting:
Answer:
Step-by-step explanation:
since the bases are the same all you have to do is just get the powers of both bases which is 3x + 1 and 10
you're then going to equate 3 x + 1 to 10 and then you have to make +1 cross to the other side making it become -1
you then can subtract 1 from 10 leaving you with 9
and at the LHS we have 3x
we are gonna get rid of the three by dividing it into itself and the 9 at the RHS then <u>X = 3</u>
