Answer:
x = 10
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation ...
Sin = Opposite/Hypotenuse
sin(30°) = 5/x
Solving for x, we get ...
x = 5/sin(30) = 5/0.5
x = 10
_____
It can be helpful to remember that the side ratios in a 30°-60°-90° triangle are ...
1 : √3 : 2
That is, the hypotenuse is 2 times the length of the side opposite the 30° angle. Here, that means x = 2×5 = 10, as we found above.
Answer:
x= 7/5
Step-by-step explanation:
11 1/5 = (11*5+1)/5=56/5
2 3/4= (2*4+3)/4=11/4
11 1/5 : 2 3/4=56/5:11/4=56/5*4/11=(56*4)/(5*11)=224/55≈4.07≈4
Answer is 4
Answer:
The correct option is C.
Step-by-step explanation:
The given function is
..... (1)
The point slope form of a linear function is
..... (2)
Where, m is slope and the graph passing through the point
.
From (1) and (2), we get

It means the slope of the line is positive and the graph passing though the point (2,4).
Put x=0 in the given function, to find the y-intercept.





The y-intercept is 1.333.
Put y=0 in the given function, to find the x-intercept.




The x-intercept is -1.
Therefore option C is correct.
Answer should be 20
4x5=20
