The correct answer is the square root of 296 which is approximately 17.20

Use the Pythagorean Theorem to solve it

a^2 + b^2 = c^2
14^2 + 10^2 =c^2
196 + 100 = c^2
196+100=square root 296

Answer:

Step-by-step explanation:

Use the Pythagorean Theorem. The hypotenuse, 14 square should be equal to the sum of x squared + 10 squared.

14^2 = 196

10^2 = 100.

So, 196 = 100 + x^2

$x = \sqrt{96}$

Find Y if AB bisects DAC and CB bisects ACE

xxMikexx [17]

Answer:

L1 and L2 are parallel

BAC = 58° as it is given in the question that AB bisects DAC

similarly BCE = y°

angle B = 90° ( from figure)

Y + 58° + 90° = 180 ( angle Sum property of a triangle).

Y + 148° = 180°

Y = 180 - 148

Y = 32°

Using the order of operations, what would be the first step:<br><br> 4−8÷1−3[3+(7−5)2]

jeka94

Answer:

(7-5)

Step-by-step explanation:

According to PEMDAS, parenthesis go first. But there are two sets of parenthesis so the one inside the other goes first.

Next would be [3+(2*2)]

Then, [3+4]

Then, -8/1

Then, -3(7)

So the question would be 4-8-21

Which gives you -25 as an answer.

I realize that you weren't asking for the whole thing but maybe there are follow up questions.

The percent error is 6.25%

Step-by-step explanation:

Percent error is given by:

$Percent\ Error=\frac{|Experimental\ Value -\ Accepted\ value|}{Accepted\ value}*100$

Here,

Accepted value = 80.0°C

Experimental Value = 75.0°C

Putting the values in the formula

$Percent\ Error=\frac{|80.0 -75.0}{80.0}*100\\=\frac{|5.0|}{80.0}*100\\=\frac{5.0}{80.0}*100\\=0.0625*100\\=6.25\%$

Hence,

The percent error is 6.25%
