Answer:

Angle P is congruent to itself due to the reflexive property.

Explanation:

Angle P must be congruent to angle S through corresponding angle theory.

Otherwise, it wouldn't prove ΔPQR is similar to ΔSTR.

Will give brainliest to correct answer.
kirill [66]
It's going to be kind of crazy, but you need to use Pythagorean's Theorem for this.  That will look like this: (2 \sqrt{x} +1)^2=( \sqrt{x} +1)^2+(2 \sqrt{x} )^2.  FOIL out the left side to get 4x+4 \sqrt{x} +1.  FOIL out the first of the 2 expressions on the right to get x+2 \sqrt{x} +1,  and the second of the 2 to get 4x.  Our equation now looks like this:  4x+4 \sqrt{x} +1=x+2 \sqrt{x} +1+4x.  Combine like terms to get an equation that still has square roots in it that we have to deal with:  4x-x-4x=-2 \sqrt{x}  and x=2 \sqrt{x}.  We will square both sides to get rid of the square root sign.  x^{2} =2x.  This is a polynomial now that can be factored to solve for x.  Bring the 2x over by subtraction and set the polynomial equal to 0.  x^{2} -2x=0.  Factor out an x, leaving us with  x(x-2)=0.  That means that x = 0 or x - 2 = 0 and x = 2.  Of course if we are solving for the length of a side we know it can't have a side length of 0, so it must have a side length that is a multiple of 2.  x = 2

Ms. Peters drove from her home to the park
worty [1.4K]

It takes 15 minutes for Ms. Peter to drive from park to her home

Given :

from her home to the park at an average speed of 30 miles per hour and

returned home along the same route at an average speed of 40 miles per hour

it takes 20 minutes to travel

Convert 20 minutes in to hour (divide by 60)

20 minutes = 1/3 hour

We know that distance = speed x time

 From home to park, distance  =speed \cdot time =30 \cdot \frac{1}{3} =10 miles

So , distance between home  and park is 10 miles

Now we calculate the time taken to return from park to home

time taken =\frac{distance}{speed} =\frac{10}{40}=\frac{1}{4}\\

Time taken is 1/4 hours. Convert it into minutes by multiplying by 60

\frac{1}{4} \cdot 60=15

So it takes 15 minutes for Ms. Peter to drive from park to her home
