C or A could be the answer
Answer:
D. sin m∠C = 2 square root of 5 all over 5
Step-by-step explanation:
The triangle ABC is a right angled triangle. The angle ∠C is where we are asked to find. The side AB measures 6 , AC measures 3 and the side BC measures 3√5.
The longest side of a right angle triangle is the hypotenuse, that means the side with length 3√5 is the hypotenuse.
Therefore side BC is the hypotenuse side and we are asked to find the angle C. AB is the opposite side while AC is the adjacent side.
Using
sin C = opposite/hypotenuse = 6/3√5 = 2/√5 = 2√5/5
cos C = adjacent/hypotenuse = 3/3√5 = 1/√5
Answer:
x=6
Step-by-step explanation:
(x-6)^2=0
Answer:
cheese=$7
sausage=$5
Step-by-step explanation:
let the cost of a pound cheese be x
that of sausage=x-$2
3x+3(x-2)=3x+3x-6
6x-6=36
6x=36+6
6x=42
x=7
