Answer:
The angle is "27 and 63".
Step-by-step explanation:
Let A and B are two angles, in which A is " 
" complementary angles and B be is another complementary angle.
Condition of complementary angle
:
Solution:
B maybe or A
Because 15 percent of 212 is 31.8 so it’s closer to 40 maybe
Answer:
4
Step-by-step explanation:
Here you need not completely solve 7992 squared. You can just take the last digit which in this case is 2 and solve for the square of that digit. 2 x 2 = 4. Now if it was a bigger digit which would result in a two digit number when squared you would take the last digit of that number. But, we don't need to do that here since 2 squared is 4.
M = mass
p = density
v = volume
Yes, to find m it would be m = pv.
To find v that would be m/p.
2/2 part of the equation is ≤ B
maybe 30/100 ≤ B
