Find the value of y.
Leno4ka [110]

Answer:

\sqrt{55}

Step-by-step explanation:

Based off of what we do know, if we can find length DB we can use the pythagorous theorem (I will be assigning the variable z)

x^{2} =36+z^{2} \\\\y^{2}=25+z^2\\\\x^{2} +y^2=121\\\\

First equation is for triangle ABD

Second is for BCD

And the last one is for ACD

Substitute x^{2} and y^2

36+z^2+25+z^2=121\\\\61+2z^2=121\\\\2z^2=60\\\\z^2=30\\\\z=\sqrt{30}

As discovered before

y^2=25+z^2\\\\y^2=25+30\\\\y^2=55\\\\y=\sqrt{55}

HElP IM GIVING BRAINILYIST
pogonyaev

Answer:

D.

Step-by-step explanation:

The difference in pizza delivered between driver A and driver B is 10 pizzas.

We can find this by doing 20-10 which is 10.

The MAD is 2.

D says that Driver A has less pizzas delivered than Driver B by 5 MADs. Since 1 MAD is 2, 5 MADs is 10.

Meaning D says that driver A delivered 10 less pizzas than Driver B, which is correct.

Hope this answer helped! :)
