Answer:12
Step-by-step explanation:
4 is the base because the formula for a triangle is base times height divided by two, you would know that 8 times 4 would equal 32. When divided by 2 it would equal 16 which is the area. So 4 is the answer.
When the points or coordinates are in bigger values.
Answer:
Step-by-step explanation:
We are to find the equation a line that passes through the point (8, 1) and which is perpendicular to a line whose equation is
.
We know that the slope of line which is perpendicular to another line is the negative reciprocal of the slope of the other line so it will be
.
Then, we will find the y-intercept of the line using the standard equation of a line:
Therefore, the equation of the line will be
.
Answer:
x = 64
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Sum the given angles and equate to 360
x + 2x + 114 + x - 10 = 360, that is
4x + 104 = 360 ( subtract 104 from both sides )
4x = 256 ( divide both sides by 4 )
x = 64
