Answer:
the measure of angle Q = 92°
Step-by-step explanation:
<u><em>The quadrilateral OPQR is inscribed inside a circle, then its opposite angles are supplementary</em></u>.
………………………………
Then
m∠O + m∠Q = 180
Then
2x + (2x+4) = 180
Then
4x + 4 = 180
Then
4x = 180 - 4 
Then 
4x = 176
Then
x = 176/4
Then
x = 44
Therefore
m∠Q = 2(44) + 4 = 88 + 4 = 92°
 
        
             
        
        
        
Answer:
378
Step-by-step explanation:
12 x 18=216
9 x 9= 81
81 x 2= 162
162 + 216 = 378
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Let x = the age of the youngest child
Let x + 1 = the age of the middle child
Let x + 2 = the age of the oldest child
x + x + 1 + x + 2 = 39
3x + 3 = 39
3x = 36
x = 12 years
 
        
             
        
        
        
The x axis is labeled as Number of days.
<h3 /><h3>What is graph?</h3>
Graph is a mathematical representation of a network and it describes the relationship between lines and points. 
let x be the  number of days and y be money.
So, the equation is
y = -7x + 150.
Hence, the x axis is labeled as Number of days.
