Find the value of y, please explain how and give the answer!

1 answer:

5 0

You would do 3x+90=180 because a straight line equals 180°. then you find x=30. then x and z add to get 180 because x fits in the slot above z so 180-30 equals 150°. if z equals 150° then 180-150 equals 30. so x=30,y=15, and z=150

babymother [125]

Answer: l = $\sqrt{34}$

Step-by-step explanation:

The slant height of a cone is given by

l = $\sqrt{h^{2}+r^{2} }$

r = 3

Therefore :

l = $\sqrt{5^{2}+3^{2} }$

l= $\sqrt{25+9}$

l = $\sqrt{34}$
