3, because a negative number multiplied by another negative number (in this case, itself) will always be a positive number.
18 is 60% of 30. I know this because 10% of 30 is 3 and 3 * 6 is 18
Answer:
B 20
Step-by-step explanation:
The complete question in the attached figure
we have that
<span>m∠4=68°
we know that
</span>m∠4 and m∠3 are supplementary angles
so
m∠3=180-m∠4----- m∠3=180-68------> m∠3=112°
m∠3 = m∠2 --------> by alternate interior angles
so
m∠2=112°
m∠1 = m∠4 --------> by alternate exterior angles
so
m∠1=68°
m∠5 = m∠4---------> by corresponding angles
so
m∠5=68°
the answers arem∠1=68°m∠2=112m∠3=112°m∠5=68°
I’m pretty sure it’s (3.63)
