Answer:
1) y = 41
2) y = 4
Step-by-step explanation:
Answer:
$21
Step-by-step explanation:
- Step one we find what 30% of $30 is, percentage is a number over 100;
, so 9 dollars- Now this is the amount of the discount, so we take it out of $30
- So $30-$9=$21
- That's the discount

(s o t)(x)=s(t(x))
(s o t)(-7)=s(t(-7))
x=-7→t(-7)=3(-7)→t(-7)=-21
(s o t)(-7)=s(t(-7))=s(-21)
x=-21→s(-21)=2-(-21)^2=2-441→s(-21)=-439
(s o t)(-7)=s(t(-7))=s(-21)=-439

Answer:
m<1: 51
m<2: 61
m<3: 29
Step-by-step explanation:
m<1 = 51, because to find the 3rd angle, you need to add the other two angles and then subtract 180 from that answer.
61 + 68 = 129
180 - 129 = 51
m<2 = 61, because it's a vertical angle, meaning that the angle that's opposite to it exactly, is the same. So since the angle opposite to m<2 is 61, that's what the answer would be.
m<3 = 29, because all you need to do is add 90 and 61, and then subtract 180 by the answer. I got 90 as one of the angle measurements because there's a right triangle, meaning it's 90. Then since we already know what angle 2 is (61) then all you need to do is add:
90 + 61 = 151
Then subtract:
180 - 151 = 29
Hello :
sin(−θ) = - sin(θ)
cot(−θ) = - cot(θ)
cot(θ) = cos(θ)/sin(θ)
sin(−θ) cot(-θ) = (- sin(θ))×(-cos(θ)/sin(θ)) = cos(<span>θ)</span>
