then they are equal in measure. 1. ∠1 is complementary to ∠2 and ∠3 is complementary to ∠2.
a) Substitution
2. m∠1 + m∠2 = 90 and m∠3 + m∠2 = 90
b) Definition of complementary
3. m∠1 + m∠2 = m∠3 + m∠2
c) Subtraction property of equality
4. m∠1 = m∠3
d) Given

1. --> d

2. --> b

3. --> a

4. --> c

1 is d because that is the only piece of information that sounds like a given.

2 is b because we know that from the given, m∠1 is complementary to m∠2 and in the first problem, m∠1 + m∠2 = 90, they are added together. The definition of complementary angles is "Two angles with measures that, when added together, equal 90 degrees". Same thing with m∠3 and m∠2.

3 is a because since both of the problems equal 90 degrees, you can just take away the 90 and put an equal sign in between the two problems because they equal the same thing.

4 is c because you are subtracting m∠2 from the problems and ending up with just m∠1 = m∠3.

Hope this helps! :)

Answer:

1.   ∠1 is complementary to ∠2 and ∠3 is complementary to ∠2.-->Given(A)

2.   m∠1 + m∠2 = 90 and m∠3 + m∠2 = 90-->Definition of complementary(D)

3.   m∠1 + m∠2 = m∠3 + m∠2-->Substitution(C)

4.   m∠1 = m∠3-->Subtraction property of equality(B)

Although there is no picture, I will assume this is a triangle we are talking about since the terms base and height are being used. If that is the case, the height is roughly 38.72in. 

To find this, we will use the area of a triangle formula. 

1/2bh = a ---> plug in known values. 
1/2(12.6)(h) = 244 ---> multiply to simplify
6.3(h) = 244 ----> divide both sides by 6.3
h = 38.73

2. Let's pretend I'd give you a penny today, two pennies
gizmo_the_mogwai [7]
Answer:
-f(n+1) = f(n) x 2
-on the 10th day you'd receive $512
-this function works by taking the output of the last input and multiplying it by 2 to find the new output.
-i'd rather take 40 days of this money scheme.

example of use:
f(10) = f(9) x 2
output of f(9) is 256 so f(10) = 256 x 2
