Answer:
-40% change
Step-by-step explanation:
- This change is a decrease, so first you need to find the difference between the two numbers--> 125 - 75 = 50
- Next, you divide by the original number, so 50 ÷ 125 = 0.4
- Finally, you multiply your answer by 100, so 0.4 x 100 = 40%. Because this is a decreasing change, you add a negative sign.
Let's first get the representation of tan
We also need to understand how to convert radians to degrees
For question 1
since tan > 1
It must be in either first quadrant or third quadrant as shown in the diagram above
Answer:
A=584.57m2 (i hope)
Step-by-step explanation:
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.
I think is A or b go try it am not 100% sure
