Answer:

Step-by-step explanation:

The square means a $90$ degree angle.

We know that all the angles in a triangle add to $180$ degrees. So, we can build an equation for x: $(2x+1)+(5x+5)+(90)=180$

Combining like terms on the left side gives $7x+96=180$

Subtracting $96$ from both sides gives $7x=84$

Dividing both sides by $7$ gives $\boxed{x=12}$

Grace [21]

Answer: $75\%$

Step-by-step explanation:

You know that the ratio of the television's screen is $5:4$ . This ratio can be also written as the following fraction:

$\frac{5}{4}$

The television shows an image with a ratio of $20:12$ which can be also written as a fraction:

$\frac{20}{12}$

Set up the following proportion and solve for "x":

$\frac{20}{x}=\frac{5}{4}\\\\x=\frac{4*20}{5}\\\\x=16$

Now, in order to find the percent of the screen area occupied make the following division:

$\% occupied=\frac{12}{16}*100=75\%$
