The equation that correctly represents the relationship between a, b, and c in the triangle is c² = a² + b² - 2ab * cos(90)
An equation is an expression that shows the relationship between two or more numbers and variables.
Cosine rule is used to show the relationship between the sides and angles of a triangle. It is given by:
c² = a² + b² - 2ab*cosC
Where a, b and c are the sides, while C is the angle opposite to side c.
In the triangle ABC, C = 90°, hence:
c² = a² + b² - 2ab * cos(90)
The equation that correctly represents the relationship between a, b, and c in the triangle is c² = a² + b² - 2ab * cos(90)

Answer: Hey! Don't worry!! I gotchu'. :D
A. To find 1/5 of 15, we can multiply 15 by 1/5, which is the same as dividing 15 by 5. So, 1/5 of 15 is equal to 15 ÷ 5 = 3.
B. To find 4/5 of 35, we can multiply 35 by 4/5, which is the same as multiplying 35 by 4 and then dividing the result by 5. So, 4/5 of 35 is equal to (35 × 4) ÷ 5 = 28.
