The measure of <span>∠</span>2 is 146°
Answer:
C
Step-by-step explanation:
The difference formula for cosine is
cos(x - y) = cosxcosy + sinxsiny
Consider
cos75 = cos(120 - 45)°, then
cos(120 - 45)°
= cos120°cos45° + sin120°sin45° → C

Answer:
It's right :)
Explanation:
- Dilation along the x-axis = (-7-1)/(-1-1) = 2/8 = 1/4
- Dilation along the y-axis = (-7-1)/(-1-1) = 2/8 = 1/4
Thus, the overall dilation is 1/4
