Answer: y=31.97°
Explanation: We can use trig ratios to find y and they are SohCahToa.
We can use Sin y, because when y is the reference angle, the 9 cm side is the opposite and the 17cm is always the hypotenuse.
We must take the inverse of Sin (9/17) to get about 31.9657, which we can round to 31.97°.

Let's use PEMDAS for this expression (parentheses, exponent, multiplication/division, addition/subtraction) Even though subtraction is first, you would multiply first because multiplication is before subtraction So multiply -(1/4) and (4/9) and you get -(1/9). Now add (2/3) and you get a final answer of (5/9)
Answer:
AT = 8
Step-by-step explanation:
Using the sine ratio in the right triangle
and sin45° = 
sin45° =
=
= 
Multiply both sides by AT
AT × sin45° = 8, that is
AT ×
= 8
Multiply both sides by 
AT = 8
