Answer:

The answer is "10.25"

Step-by-step explanation:

Please find the graph in the attachment:

In the given kite diagram the PT= TR so,

in  \Delta QTR we applying the Pythagoras theory:

\to QR^2=QT^2+TR^2\\\\\to  13^2=QT^2+8^2\\\\\to QT^2= 13^2-8^2\\\\\to QT^2= 169-64\\\\\to QT^2=105\\\\\to QT=\sqrt{105}\\\\\to QT= 10.2469508\\\\ \to QT= 10.25

The legs of a right triangle measure 8 cm and 6 cm respectively. How long is the longest side of the triangle?
Masja [62]

Answer:

b. 10

Step-by-step explanation:

Based on the Pythagoras Theorem, the longest side of a right-angled triangle is: \sqrt{a^{2}+b^{2} } where a and b are the legs of the triangle.

Longest side of triangle = \sqrt{8^{2}+6^{2}}

                                        = \sqrt{64+36}

                                        = \sqrt{100}

                                        = 10

(у-4) (3x+5y-2) How do I multiply the following expression?<br>​
muminat

Answer:

3xy + 5y^{2}  - 12x - 22y + 8

Step-by-step explanation:

You will use the FOIL method, which is very similar to the distributive property.

In order to do multiply correctly, multiply the y by 3x, 5y, and -2. You should get:

3xy + 5y^{2}  - 2y

Then multiply the -4 by 3x, 5y, and -2 where you should get:

- 12x - 20y + 8

By using the foil method, you got rid of the parentheses. Now you can simply combine like terms and get your final answer:

3xy + 5y^{2} - 12x - 22y + 8

I hope this helps you!
