Answer:
A ) Substitute the side lengths of a and b in the equation
Step-by-step explanation:
The hypotenuse which is opposite the right angle it always the length of C in the cosine rule.
Answer:
(6, 5)
Step-by-step explanation:
-3 + 9 = 6
15 - 10 = 5
Answer: No mistakes was made
Step-by-step explanation:
Because It all equals the same as the answer
Given:
The side of square = 12 in.
Scale factor of enlargement = 3 in : 2 m
To find:
The proportion that is use to solve the side length, x, of the enlarged square.
Solution:
Let, the side of length of enlarged square = x m
In case of enlargement the corresponding sides are proportional.



Divide both sides by 3.


Therefore, the required proportion is
and the side length of the square after enlargement is 8 m.
