Can someone explain this plz and make sure u round to the nearest tenth
bonufazy [111]

Step-by-step explanation:

According to figure,Taking angle 49° as reference angle,we have

b=26

h=x=?

Now,

\cos49  =  \frac{b}{h}  \\  \cos49   =  \frac{26}{x}  \\ 0.66 =  \frac{26}{x}  \\ 0.66x = 26 \\x =  \frac{26}{0.66}  \\ x = 39.39 \\ x = 39.4

Please help me, I have a test tomorrow! Attachment bellow:
katrin2010 [14]

Answer:

1. A    2. B

Step-by-step explanation:

Whatever happens to x must also happen to y.

For the first question, x is doubled, which means that the value of y is also doubled.

For the second question, if the value of x triples, then the value of y triples as well, which means that it would be multiplied by 3.

We can check to see if these two answers are true by inputting values into the equations.

For the first equation, let's use the example x = 2

y = 5(2)

y = 10

If the value if x doubled, it would become x = 4

y = 5(4)

y = 20

As you can see, when the value of x doubled from 2 to 4, the value of y also doubled from 10 to 20.

You can do something similar for the other equation.
