Answer:
And find it all urself
Step-by-step explanation:
Answer:
B) BC'= 8, m A'= 28°
Step-by-step explanation:
When dilating a figure, it increases its size or decreases. In this case, as it is dilating by a factor of 1/2, you can assume it decreases.
To find the value of the new figure, A'B'C', you have to multiply the factor times the lengths of the triangle, or, the only one they are asking for in this case, the length BC':
- BC' = BC×1/2
- BC' = 16×1/2
- BC' = 8
The angles, otherwise, do not change. When figures are dilated, they are similar. The properties of similar figures are that they have congruent angles, therefore, the same angles. They do not have any effect caused by the factor, so m A' stays at 28°.
Answer:
3,468?
Step-by-step explanation:
I think the prompt is a little confusing, but I went with the logic of literally using the numbers and combining them.
4x+1=2x+7
-1 -1
4x=2x+6
-2x -2x
2x=6
2x/2- 6/2
X=3
Y = 2x^2 has a wider graph
