Answer:
x = 90°
Step-by-step explanation:
Using the identity
cos²x = 1 - sin²x
Given
cos²x - sin x + 1 = 0
1 - sin²x - sin x + 1 = 0
- sin²x - sin x + 2 = 0 ← quadratic equation in sin x ( multiply through by - 1 )
sin²x + sin x - 2 = 0 ← in standard form
(sinx + 2)(sinx - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
sinx + 2 = 0 ⇒ sinx = - 2 ← has no solution as - 1 ≤ x ≤ 1
sinx - 1 = 0 ⇒ sinx = 1 ⇒ x = 90°
solution is x = 90°

Answer- 
Step-by-step explanation:
First, we will write and equation in point-slope form and then convert to slope-intercept form.
To use the point-slope form we must first determine the slope.
The slope can be found by using the formula :
<em>Where </em>
is the slope and
) are the two points on the line.
Substituting the values from the points in the problem gives:
We can now use this calculated slope and either point to write the equation in point-slope form.
The point-slope formula states: 
Where
is the slope and
is a point the line passes through.
Again, substituting gives:
We can now convert this to slope-intercept form.
The slope-intercept form of a linear equation is:
Where
is the slope and
is the y-intercept value.
We can solve our equation for
