I want to say it is an acute angel
Answer:
$18.375 or rounded = $18.38 (brainliest if correct)
Step-by-step explanation:
25.00- 7.5 = $17.5
5% of 17.5 = 0.875
17.5 +0.875 = 18.375
Here: Fraction = 3/5
Let, original fraction (before simplifying) = 3x/5x
Then, 3x + 5x = 40
8x = 40
x = 40/8
x = 5
So, 3x = 3(5) = 15 & 5(5) = 25
In short, Your Answer would be 15/25
Hope this helps!
First, we expand the equation:

Then, we combine certain terms in order to simplify them using trigonometry identities.

Note these identities:
