2 to the negative 1 power. When you divide two exponents with the same base, you subtract the two exponents to get your answer.

Answer:
1st one
Step-by-step explanation:
Because It is just like a right triangle.
Also, look at how the bird is formed, it looks like a right triangle.
Also, I know it's a right triangle because of the length given.
Hope this helped!
Answer:
D irrational number
Step-by-step explanation:
because you do the Pythagorean theorem and you get 7.81024976 and that is a irrational number
Since only the lengths increase by scale factor, B'C' on the same line as its corresponding side segment BC .
<u>What is the Dilation?</u>
Math definition of dilation Resizing an object is accomplished through a change called dilation. The objects can be enlarged or shrunk via dilation. A shape identical to the source image is created by this transformation. The size of the form does, however, differ.
The following are the properties of dilation of the triangle:
1)measures of the angles will not change
2)The sides of the image of the triangle are multiplied by the scale factor 2.
So,
A'B'=2AB
B'C'=2BC
A'C'=2AC
Since only the lengths increase by scale factor, B'C' on the same line as its corresponding side segment BC .

Answer:
∠B = 53°
∠C = 127°
∠D = 127°
Step-by-step explanation:
The trapezoid is isosceles, as indicated by the hash marks on sides AD and BC. This means it is symmetrical about the vertical center-line. Angles on the right will have the same measures as the symmetrical angles on the left.
So, you know immediately that ∠B = ∠A = 53°.
Because AB ║ DC, ∠A and ∠D are supplementary. That is, ...
∠D = ∠C = 180° -53°
∠D = ∠C = 127°
