Type the correct answer in the box.<br><br><br> In this triangle cosA/cosB= blank
Elina [12.6K]

Answer:

1

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.  

Trigonometric functions are used to show the relationship between the angles of a triangles and the sides of the triangle. For a right angled triangle, the ratio of the sides can be gotten using trigonometric functions such as:

cosθ = adjacent/hypotenuse, sinθ = opposite/hypotenuse, tanθ = opposite/adjacent

Given the right angle triangle:

cos(A) = adjacent / hypotenuse = 3 / 4.24

cos(A) = 3 / 4.25

cos(B) = adjacent / hypotenuse = 3 / 4.24

cos(B) = 3 / 4.24

cos(A) / cos(B) = (3 / 4.24) ÷ (3 / 4.24) = 1

cos(A) / cos(B) = 1

Classify the following expression by degree and term: x^3y + 5xyz A: 3rd degree trinomial B: 4th degree binomial C: 3rd degree b
drek231 [11]

Answer:

4th degree binomial

Step-by-step explanation:

x^3y + 5xyz

Add the exponents on each term

3+1 = 4     1+1+1 =3

The highest power is the degree, so it is a 4th degree

It also has 2 terms so it is a binomial

4th degree binomial
