Sandra's quarterly report from her investment account shows that she made a gain of $210. That gain included a one-time per year credit of $30. Sandra used the equation
1 (x +30) = 210 to project how much money, x, her investment account will earn
during the year, excluding the one-time credit. How much money will Sandra's account
earn during the year, excluding the one-time credit?

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

answer: ok

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
