Answer:
B = 129
Step-by-step explanation:
Opposite angles of a parallelogram are equal (or congruent)
A and C are both 51.
All angles in a parallelogram equal 360
Take both the known angles and substract from 360, than divide by 2.
B = (360 - 51 - 51)/2
B = 129
Answer:
Angle b = 30 degrees
Step-by-step explanation:
3x = 90.
X= 30
Angle b = 30 degrees
Show the diagram please so I can figure the answer out
Since you need to dilate the scale factor by four, I am pretty sure you would just multiply each value by 4
19(4) = 76
16.5(4) = 66
27(4) = 108
21(4) = 84
16(4) 64
