Answer:
55deg
Step-by-step explanation:
Since ABC is similar to DEF,
angle A = angle D
angle B = angle E
angle C = angle F
therefore, angle E = 55deg
this is a topic on congruence and similarity.
if you would like to explore more into this topic you can give me a follow on Instagram (learntionary) I'll be posting the notes for this topic soon and will also be posting other topics' notes and some tips :)
Remember that cos(0) represents the x value of a point on the unit circle. The period for the unit circle is 2π in radians which means that adding or subtracting 2π will get you back to the same point which has the same cosine.
Examples: cos(2π),cos(100π),cos(60π)
9,500 just add the 0 always add 0 if you multiply by 10. 00 for 100 and 000 for 1000
No it is not because <span>0% of 10% of 100 which can be written like </span>10%(10%100) = 1 while 20% of 100 is 20
Answer:
-1
Step-by-step explanation:
2(.5n-3)=n-0.25(12-12n)
first you distribute whatever is on the outside of the parenthesis to the inside of the parenthesis
1n-6=n-3+3n
then you combine like terms and end up with
1n-6=-3+4n
add 6 to each side to get
n=3+4n
subtract 4n from each side to get
-3n=3
divide -3 from each side to get
n=-1
