9,6^2+18,8^2=X^2
92,16+353,44=X^2
X^2=445,6
X=21
Answer:
y² -7y+12
Step-by-step explanation:
first, you have to multiply each character on the first parenthesis to the second one, one by one. just like the picture attached.

Answer:
5/3
Step-by-step explanation:
Trigonometric ratio
Cot θ = Adjacent side/Opposite side
It is given that,
Cot θ = 4/3
Adjacent side = 4
Opposite side = 3
Csc θ = Hypotenuse/Opposite side
To find the Hypotenuse
Hypotenuse² = Opposite side² + Adjacent side ² = 3²+ 4²
Hypotenuse = √(3²+ 4²) = 5
To find Csc θ
Csc θ = Hypotenuse/Opposite side = 5/3
