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

What is the sum of 2x+1 and its opposite?

Masja [62]

Answer:

Zero. The sum of anything and it's opposite is zero, that's how an opposite is defined . In this case, the opposite of 2x+1 is -(2x+1)=-2x-1 by the distributive property . Adding like terms, 2x+-2x+1+-1=0+0=0.

Is the relationship proportional or not? Explain. y=0.25x

givi [52]

Yes, it is Proportional.
Y=0.25x
For example:
If x=1, y=0.25
If x=2, y=0.5
So, it is proportional.
