Hey there!

As you can see, they are lying on the same line.

When two angles are on the same straight line, they are adjacent.

Adjacent angles are supplmentary.

Adjacent angles= 180 degrees Supplementary= 180 degrees

They are choices "A" and "B".

I hope this helps!

Can someone please give me the right answer.

Answer:

Y=106

X=18

Step-by-step explanation:

Both sides would have 65° because of the Alternet interior angles.

180° minus the 65° gives you 115° when you solve for X and solve for Y Use the 115° as shown in the photo below

Pratap puri rowed 10 miles down a river in 2 hours, but the return trip took him 2 and one half hours. Find the rate pratap can

N76 [4]

Answer:

<em>Rate of Pratap in still water is 4.5 miles/hour and rate of current is 0.5 miles/hour.</em>

Step-by-step explanation:

Pratap Puri rowed 10 miles down a river in 2 hours, but the return trip took him 2.5 hours.

We know that, $Speed = \frac{Distance}{Time}$

So, the <u>speed of Pratap with the current</u> will be: $(\frac{10}{2})miles/hour = 5$ miles/hour

and the <u>speed of Pratap against the current</u> will be: $(\frac{10}{2.5})miles/hour = 4$ miles/hour.

Suppose, the rate of Pratap in still water is $x$ and the rate of current is $y$ .

So, the equations will be........

$x+y= 5 .............................. (1)\\ \\ x-y=4 .............................. (2)$

Adding equation (1) and (2) , we will get......

$2x=9\\ \\ x=\frac{9}{2}= 4.5$

Now, plugging this $x=4.5$ into equation (1), we will get.....

$4.5+y=5\\ \\ y=5-4.5 =0.5$

Thus, Pratap can row at 4.5 miles per hour in still water and the rate of the current is 0.5 miles/hour.

Hello!

The quadratic formula is

$x = \frac{-b +- \sqrt{ b^{2}-4ac } }{2a}$

So the answer is D

Hope this helps!
