What fraction of the rectangle is shaded? write your answer as a rational expression in simplified form.

The fraction of the rectangle that is shaded is equal to the ratio of the area of triangle and the are of rectangle. First, we need to determine the value of x to be able to calculate the respective areas. We do as follows:

From the triangle,

tan 45 = 2 / (x/2)
1 = 4 / x
x = 4

L = 4 + 2 = 6
W = 4

A(triangle) = hb / 2 = 2(4) / 2 = 4
A(rectangle) = LW = 6(4) = 24

Fraction shaded = 4 / 24 = 1/6

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
