Step-by-step explanation:
Hence it is a triangle So sum of all the angels of triangle is equal to 180°
Then
5x + 6x + x = 180°
12x = 180°
x = 180° / 12
x = 15°
5x = 5*15°= 75°
6x = 6* 15° = 90°
x = 15°
Hope it helps :)
Answer:
I will show all the steps to lead to the solution.
1) 10b = 5 (√c + 2) <---- starting equation
2) divide by 5 => 2 b = √c + 2
3) subtract 2 => 2b - 2 = √c
4) raise to the power 2 => (2b - 2)^2 = c, which is the expression given.
Now these are two equivalent forms:
1) extract 2 from the parentheses: c = 4 (b -1)^2
2) expand the parentheses: c = 4b^2 - 8b + 4)
