Answer:
C = ¼(4B – 7A)
Step-by-step explanation:
⁴/₇(B – C) = A Multiply each side by 7
4(B - C) = 7A Remove parentheses
4B – 4C = 7A Subtract 4B from each side
-4C = 7A – 4B Multiply each side by -1
4C = -7A + 4B Divide each side by 4
C = ¼(4B – 7A)

I hope I have helped you . Complete those steps left from right and you should get it .
A right triangle is formed with the equation a^2 + b^2 = c^2
For example 7, 24, 25 is a right triangle
7^2 + 24^2 = 25^2
49 + 576 = 625
625 = 625
For example 20, 25, 30 is NOT a right triangle
20^2 + 25^2 = 30^2
400 + 625 = 900
1025 does not equal 900
Answer: the answer is 10
Step-by-step explanation: divide the sector area and measure 90 divided by 9 = 10
