Answer:
x= 63
Step-by-step explanation:
all angles in a triangle add up to 180.
76 + 41 = 117
180 - 117 = x
x = 63
Hope this helps :)
Answer:
5x² + 7x + 7
Step-by-step explanation:
Subtract 3 from 10
3x+5x²-x+7+5x
Subtract x from 3x
5x² +2x+7+5x
Add 2x and 5x to get the 7x
It’s B because
Explanation: Since they've given use the area of the triangle, we can use the area formula to find the base of the triangle. The formula to find the area of a triangle is: a=12hb.
Answer:
Enlargement transformation
Step-by-step explanation:
A dilation is a transformation which produces an image of the same shape as the original, but may/may not be of the same size. A dilation could be an enlargement, reduction or a congruence.
The following rule applies(given the scale factor k)
- If k > 1, there is an enlargement.
- If 0 < k < 1, there is a reduction.
- If k = 1, there is a congruence.
therefore, since k=6/5=1.2>1, there is an enlargement transformation
