Answer:
24°
Step-by-step explanation:
Complementary angles are the angles whose measurements equal to 90°
To find the complement of 66 you subtract it from 90
90 - 66 = 24
12 + 42 is 54. If you take the numbers apart and add them into tens. 42 because 4 10s and your left with 2 ones. If you take 12 and seperate it into tens you get 1 ten with a remainder of 2. 10 + 10 + 10 + 10 + 10 = 50. 2+2 is 4. Remember that they are the same number so 50 + 4 is 54.
Answer:
5 x 2 inside the parenthesis
Step-by-step explanation:
We need an order of operations to ensure we always arrive at the correct answer. It gives us a consistent way to work with numbers. We use the mnemonic device like PEMDAS to remember the correct order.
P-parenthesis
E-exponents
M-multiplication
D-division
A-add
S-subtract.
We apply them left to right doing inner operations before outer operations.
There fore our first step is in the parenthesis and multiplication because it is the inner most operations. 5 x 2 inside the parenthesis.
