Step-by-step explanation:
Hey there!
PEMDAS simply means (the OVERALL question answer)
• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction
Here’s an example
24 - 4^2 + 2 * 4
= 24 - 16 + 2 * 4
= 24 - 16 + 8
= 8 + 8
= 16
Thus, the answer for that equation is: 16
Often people remember PEMDAS by saying. (So, I’d advise you think of it like that way as well!)

Good luck on your assignment & enjoy your day!

Although there i no triangle given as the question requires, I am still going to answer because I understand it.
ABC is a right angled triangle. The triangle is 90° at C.
The trigonometric ratio sine is given by, sine = opposite/hypotenuse .
Cosine = adjacent/hypotenuse
So therefore, Sin A = 24/30
= 4/5
Cos A = 18/30
= 3/5
The correct answer would be 72.7%
7 because the square root of 49 is 7, so its approximately 7.
