Answer:
40 degrees
Step-by-step explanation:
using 180 minus 94 we can find the inner left angle of the triangle as 86 degrees and using 86 plus 54 we get 140. 180 minus 140 for the last angle F so 40 degrees
A (1,-2) B(10,1) C(6,2)
You add 4 to the x value and subtract 3 from the y value to get the answer.
225.5 sq. mm
triangle:5x(9+4+4+4)=15x21÷2=157.5
5x(4+4)=5x8=40
7x4=28
157.5+40+28=157.5+68=225.5
