These are two similar triangles. What is the measure of y?
15
X
3
У.
6
y = [?]

7.5

Step-by-step explanation:

10

Step-by-step explanation:

6 / ( 3 + 6 ) = y / 15

6 / 9 = y / 15

2 / 3 = y / 15

3 * y = 15 * 2

y = ( 15 * 2 ) / 3

= 5 * 2

y = 10

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
