Answer:
46
Step-by-step explanation:
Solution :
Remember that the sum of complementary angles is always 90°.
First, finding the value of x :
Set up an equation :
( Being complementary angles )
Solve for x
{ Remove unnecessary parentheses }
{ Combine like terms }
{ Subtract 3 from 30 }
{ Move 27 to right hand side and change it's sign }
{ Subtract 27 from 90}
{ Divide both sides by 9 }
The value of X is 7°
Now, Replacing the value of x in order to find the value of B
{ Plug the value of x }
{ Multiply 7 by 7 }
{ Subtract 3 from 49 }
The measure of B is 46°
I believe the answer is, 2) End of Reconstruction
Im not sure but i think its 45+9 x X
small x= times
big X = scenario
Answer: 72.4
Step-by-step explanation:
Fraction of six-grade students that have at least one pet = 2/5
Number of sixth graders at Brunswick Elementary school = 181
The number of sixth graders that own own pets will be:
= 2/5 × 181
= 72.4
