Answer:
Step-by-step explanation:
At the point where two line cut across, the vertically opposite angles formed are equal. This means that
2x degrees = 78 degrees
Dividing the left hand side and the right hand side of the equation by 2, it becomes
2x/2 = 78/2
x = 39
Checking,
The sum of the angles on a straight line is 180 degrees.
180 - 78 = 102 degrees
2x + 102 = 180
2x = 180 - 102 = 78
x = 78/2 = 39
Answer:
10,000 m/square
Step-by-step explanation:
we know that
A hectare is a unit of area equal to 
The symbol is Ha
<em><u>Verify each case</u></em>
case 1) 10,000 m/square
The option is true
case 2) 100 m/square
The option is false
case 3) 100,000 m/square
The option is false
Answer:
Using the slope-intercept form, the slope is 4 .
They are alternate interior angles so they add up to 90.
8x-4+60 = 90 would be the equation.
Now, just combine the like terms.
8x+56 = 90
8x = 34
x = 4.25
