Solve the equation for principal values of x. Express solutions in degrees.

2 sinx - 1 = 0

a. 90

C. 315

b. 45

d. 270

Nome of the above options are correct

x = 30° or 150°

Step-by-step explanation:

2 sinx - 1 = 0

2sinx = 1

sin x = (1/2)

x = sin⁻¹ (0.5) = 30°

But sin x is positive in the first and the second quadrant,

x = 30° or 150°

Hope this Helps!!!

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
