Answer:
Rotation
Step-by-step explanation:
A transformation of a triangle can be either dilation or reflection or rotation or a translation.
Dilation happens when a symmetric figure is formed with scale factor other than 1. But here both triangles have same side length. Hence no dilation
Reflection happens when it is reflected over a line as we see in a mirror. But here the two triangles are not looking as images on a line. Hence no reflection
Rotation is keeping the same shape but rotating through a certain angle. Here DEF is rotated without disturbing its shape or size through a certain angle. Hence rotation is right
Translation is not right because there is no vertical or horizontal shift to get new triangle.
Answer:
is the measure of an angle that is the supplement of angle K=180-150=30
A.is your answer
Answer:
C)
Step-by-step explanation:
16x - 7 = 11x - 32
16x - 11x = -32 + 7
5x = -25
x = -5
__________________________________________________
-4x - 10 = 2x + 20
-4x - 2x = 20 + 10
-6x = 30
x = -5
X^2^4 = x^8
Just multiply then 2 and 4 to get 8
Answer:
1.)21°
2.)51°
3.)73°
4.)50°
Step-by-step explanation:
1.) 90° - 69°
= 21°
2.) 90° - 39°
= 51°
3.) 90° - 17°
= 73°
4.) 90° - 40°
= 50°
