Answer:
372 in ^2
Step-by-step explanation:
Wrapping a present is surface area
SA = 2( lw+wh+hl)
= 2 ( 12*3 + 12*10 + 3*10)
= 2 ( 36+120+30)
= 2 (186)
= 372 in ^2
Answer:
2. 40
3. 40
4. 140
5. 140
6. 40
7. 40
8. 140
Step-by-step explanation:
angles 2 (and 3) are supplementary angles of the given angle, this means that the given angle and either one of the two angles i just mentioned should add up to 180
angle 4 is vertical to the given, so this means that they are congruent
angle 8 corresponds to 4 and 5 corresponds to the given, so they are all congruent
angles 7 and 6 correspond to 3 and 2, so they are also 40
Answer:
its a square, so all sides similar
28. SV = RT/2 = 5.7/2 = 2.8
29. RT^2 = RQ^2 + QT^2
--> RT = √
(4^2 + 4^2)
RT = √32 =5.7
30. perimeter of RVS = 2.8 + 2.8 + 4 = 9.7
Answer:
I think the answer would be 3 minutes 32 seconds. I hope this helps.
