x = 189
Explanation: The expression x128 .(x-61)º can be simplified as x(x-61). To solve for x, set x(x-61) equal to 128 and solve for x:
x(x-61) = 128
x^2 - 61x = 128
x^2 - 61x - 128 = 0
(x-128)(x+1) = 0
Since x cannot be negative (as the original expression uses degrees), x = 128.
Solve for x128 .(x-61)º (1 point)Responsesx = 113x = 113x = 189x = 189x = 119x = 119x = 52
