Line 1 to 2: Commutative Property of Multiplication, because all that changed was the order of the things being multiplied.
Line 2 to 3: Commutative Property of *Addition*, because all that changed was the order of the things being added.

All that changed in either step was the ordering of the things being multiplied or added. That’s the commutative property.

It's c 18, because the diameter is the longest chord so it would be greater than 15.

What is the answer to this?

Answer:

Y = 28.31

Z = 13.29

Angle A = 28

Step-by-step explanation:

For Angle A:

Remember a triangle has a total of 180 degree angles. So set up your formula as

180 - 62 -90 = Angle A

For Y:

The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.

sin (B) = opp/hyp or b/c or (y)

sinB = 62

b = 25

Rewrite as c=b/2SinB -> c=25/sin62 -> Y = 28.31

For Z:

Use the Pythagorean theorem to find the unknown side.

$z^{2} = 28.31^{2} - 25^{2}$

z = 13.29
