The rules are very simple: an angle is acute if it's less than 90°, whereas it is obtuse if it's more than 90°.
So, for the first task, you just need to compare the given angle with 90°. If the angle is less than 90°, it's acute. Otherwise, it's obtuse.
Moving on, angle B is complement of a angle A if A+B=90. So, for example, the complement of the first angle is 80, because 10+80=90. Note that this implies that obtuse angles don't have a complement.
Finally, angle B is supplement of a angle A if A+B=180. So, for example, the complement of the first angle is 170, because 10+170=180.
Answer:
6(5·7)
Step-by-step explanation:
Given function:
- 30+42
- to find the answer using distributive property..
what distributive property is:
- to find the greatest common factor and then multiply using parentheses.
Factoring out the greatest common factor:
·
·
Rewrite the expression using parentheses:
·
Therefore, with using distributive property, we can change the expression 30+42 into 6(5·7).
