180-90=90
90=2x+7+45=2x+52
2x=90-52=38
x=19
v.
angle COD=3x+10
180-3x+10-2x
180+10=2x+3x
190=5x
x=38
The solution to the equation is x = 7 , -2 , Option C and D is the right answer.
<h3>What is an Equation ?</h3>An equation is a mathematical statement formed when two algebraic expression are equated by an equal sign.
It is given that the equation is
Taking square on both sides
3x-5 = (x-3)²
3x-5 = x² +9 -6x
x² -9x -14 = 0
x² -7x +2x -14 = 0
x(x-7) +2(x-7) = 0
(x-7)(x+2) = 0
x =7 , x = -2
Therefore the solution to the equation is x = 7 , -2 , Option C and D is the right answer.
