Given: The length of side x is 89.75 cm.

Answer:
y= 155.45 cm
Explanation:
To solve this, we will need to use the Law of Sines
This states that:
Firstly, we need to find the sin of angle y. As this is a 30-60-90 right triangle, we know that the angle must be 60 degrees
Now that we have side x, the angle X, and the angle Y, we can solve for the side y using the Law of Sines
Lets plug in our known values into the equation
Next we can solve for y
When plugged into a calculator, you get the value of 155.45 cm for side y

Answer is a
*The correct answer is IJ = JK
•explanation:
Given:
AB is the perpendicular bisector of
IK. ⇒ AB divides the line segment IK in two equal parts i.e. IJ = JK and the angle formed at the point of intersection J is 90° ⇒ ∠AJI = 90°. In ΔAIJ, By angle sum property of a triangle ∠AJI + ∠AIJ + ∠IAJ = 180° ( But ∠AJI = 90° ) ∠AIJ + ∠IAJ = 90° ⇒ ∠IAJ < 90° So, ∠IAJ is not a right angle. Its not given IK is a perpendicular bisector so AJ = BJ need NOT be true. As A does not lie on the line IK so A can not be the mid point of IK.
•Hence, we conclude the correct statement is IJ = JK
