Which figure has reflection symmetry?

The first triangle does. That's the right answer.

Answer with explanation:

The Meaning of the term Reflection Symmetry is that, the line which divides the geometrical shape into two congruent Parts.

First one is Isosceles Triangle, Second one is Trapezoid, Third one is Closed shape , fourth one appears Scalene Triangle.

There is no line in a trapezoid through which the two parts appear congruent to each other, neither that line can be found in closed curve nor in Scalene triangle.

But , if you draw a line through that vertex of Isosceles triangle where two equal congruent Sides intersect, then that line will be Reflection symmetry of line.

Option A

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
