Answer:
107.5 cm
Step-by-step explanation:
find the length of the missing side of triangle which is 22.5 rounded then add all the sides together
Answer:
Angle 1 - 24 degrees
Angle 2 - 48 degrees
Angle 3 - 66 degrees
Angle 4 - 66 degrees
Angle 5 - 24 degrees
Angle 6 - 66 degrees
Angle 7 - 132 degrees
Step-by-step explanation:
I wanted to get this too you as fast as possible. I will add a detailed explanation in the comments.
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! :)
