Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
<em />
We have the slope 
, and the y-intercept <em>b = -1.</em>
Substitute:
5+x

Simplify √-y to √yi
3+ 2y = √yi
Square bot sides
(3 + 2y)^2 = -y
Expand
9 + 12y + 4y^2 = -y
Move all terms to one side
9 + 12y + 4y^2 + y = 0
Simplify 9 + 12y + 4y^2 + y to 9 + 13y + 4y^2
9 + 13y + 4y^2 = 0
Split the second term in 9 + 13y + 4y^2 into two terms
4y^2 + 9y + 4y + 9 = 0
Factor out common terms in the first two terms, then in the last two terms
y(4y + 9) + (4y + 9) = 0
Factor out the common term 4y + 9
(4y + 9)(y + 1) = 0
Solve for y
y = -9/4, -1
Check solution
when y = -9/4, the original equation; 3 + 2y = √-y does not hold true. We will drop y = -9/4 from the solution set.
Therefore,
<u>y = -1</u>
The angle of X would equal 104 degrees. The reason behind that would be because it is a vertical angle, meaning it equals the same amount vertical to itself.
To get angle Y, you would need to add 104 and 56 together (160) to find the last angle. Knowing that all triangles equal 180 degrees, you subtract 160 from 180, resulting in 20 degrees. The angle of Y equals 20 degrees.
X = 104 degrees
Y = 20 degrees
