Answer:
The angles are 69.2 degrees and 20.8 degrees
Step-by-step explanation:
Complementary angles, when added together, = 90°
We’ll call the first unknown angle a and the second angle b
b = a - 48.4
a + b = 90
So let’s substitute in for b in the second equation:
a + a - 48.4 = 90
2a - 48.4 = 90
2a = 138.4
a = 69.2
69.2 - 48.4 = 20.8 = b
Now, does a + b = 90?
69.2 + 20.8 = 90

Answer:
See below
Step-by-step explanation:
Find angle A by subtracting the others from 180
180 - 81 - 17 = 82
Put in order from least to greatest
Angles: B, C, A
Then the opposite sides will follow the same pattern, so they are
Sides: AC, AB, BC
Answer:
48 different houses can be designed from these plans.
Step-by-step explanation:
There are four options:
O1 - O2 - O3 - O4
O1 is the number of different living rooms. So O1 = 3.
O2 is the number of different bedroom configurations. So O2 = 4.
O3 is the number of different garage styles. So O3 = 2.
O4 is the number of different outside configurations. So O4 = 2.
In all,
48 different houses can be designed from these plans.

Answer:
PEMDAS
Step-by-step explanation:
Using PEMDAS or the order of operations, you first multiply 2 by 6
2-2×6+3
2-12+3
Then you can go in any order since addition and subtraction take the same precedence.
-10+3=-7
