let : y = Opponent side, x= Adjecent side
and r= hypotenuse
tan = 4/5
y/x = 4/5 => y =4, x=5
so, r = √4²+5²=√16+25=√41
sin = y/r = 4/ √41
cos = x/r = 5/√41
tan = y/x = 4/5
csc = r/y = √41 /4
sec = r/x = √41 /5
cot = x/y = 5/4
Your answer is A=1.2(2x+3)
Answer:
75 in²
Step-by-step explanation:
(see attached for reference)
recall that the formula for area of a circle is given by
Area = π r²
where
π = given to be 3
r = radius given as 5 in
simply substituting the values into the equation:
Area = π r²
= 3 x 5²
= 3 x 25
= 75 in²
Step-by-step explanation:
The area of a triangle is 1/2×width×length. Volume of a triangular prism is 1/2×width×length×height.
Fill in and we get 1/2×10×length×4=140. length=(140×2)/(10×4)=280/40=7. So you're right.
Answer:
D) 
Step-by-step explanation:
Area = Length * Breadth
Area = 
Apply exponent rule: 
Therefore,
Area = 
Area = 
Apply exponent rule as mentioned above:
Area = 
Area =
