The value of x is more 90 because the angle is an obtuse and an obtuse is more than 90 degrees.
Consider re-writing this formula as "A = pi*r^2." The backslash symbol "\" is unnecessary.
If A = pi*r^2, and we wish to solve for r, then divide both sides by pi:
A/pi = r^2
Taking the square root of both sides, sqrt(A/pi) = r (r must be positive in this situation).
78, because you have to do the inverse operation so 80/2= 40 then 40-1= 39 and 39*3 = 78
Answer:
a equals 105°
Step-by-step explanation:
angles in a straight line add up to 180°
a+75=180
a=180-75
a=105°
Answer:
Vertical
Step-by-step explanation:
Vertical line crossing the x-axis at 6. It does not cross the y-axis.
