Answer:
A
Step-by-step explanation:
If you follow the dotted lines and bring all the lines together,
angle8 = angle4 (corresponding angles)
angle8 = angle5 (vertically opposite angles)
angle5 = angle1 (corresponding angles)
Therefore, angle8 is basically the same as angles 1 and 4
Thus,
127+127=254
Answer:
P = 6.4 m
Step-by-step explanation:
Hello,
The perimeter is the sum o each side of that square, so:
Psquare = 4*(lenght of side)
P = 4*(1.6m)
P = 6.4 m
PD: PI IS NOT NECESSARY, WORKS ONLY FOR CIRCLE
Best regards
