x = 2
Step-by-step explanation:
Answer:
<h2>
<em><u>the step curve</u></em></h2>
<em>The greatest integer function graph is known as the step curve because of the step structure of the curve. Let us plot the greatest integer. First, consider f(x) = ⌊x⌋, if x is an integer, then the value of f will be x itself. If x is a non-integer, then the value of x will be the integer just before x.</em>
Answer:
50°
Step-by-step explanation:
Given figure is a quadrilateral. Sum of the measures of all the angles of a quadrilateral is 360°.
Therefore,

Take 1/2 of 1 and square it and add to both sides
1/2 squared=1/4, add to both sides
x^2+x+1/4=19/4+1/4
factor perfect square
(x+1/2)^2=20/4
(x+1/2)^2=5
square root both sides
x+1/2=+/-√5
minus 1/2 both sides
x=-1/2+/-√5
x=-1/2+√5 or
x=-1/2-√5
