Arrange the steps in the correct order to solve this trigonometric equation 2sin^2 x -sinx -1 =0 for 0 degrees is less than or equal to x is less than or equal to 90 degrees

Step-by-step explanation:

Given the trigonometry equation;

Step 1; Let p = sin(x) to have;

Step 2: factorize the resulting quadratic equation:

Step 3: Find x:

when p = 1

sin(x) = 1

also when p  -1/2

sin (x) = -1/2

Since 150° is not within the range 0<x<90, then the only solution is 90°

it would be:

c.parallelogram.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
