If Sin is 11/20

What is Cos?

COS is 59/20

Step-by-step explanation:

from trigonometry basics we have SOH CAH TOA

SOH means sine = opp/hypo

CAH means  cos = adj/ hypo

TOA  means tan = opp/ adj

in a right angle triangle the sum of sides is equal to 90degree

if  sine = 11/20 the it means the the opposite(OPP) = 11 while the Hypotenus side(Hyp) = 20

then we have to find our adjacent , 11+20+ adj= 90

31+ adj =90

adj = 90-31

adj= 59

therfore, COS = ADJ/HYP

COS= 59/20

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
