Answer:
58
Step-by-step explanation:
The sum of the exterior angles ALWAYS measures 360 degrees, meaning that 90+38+3x+x = 360
This means that 128 + 4x =360, meaning that 4x = 232.
That makes x = 58
To find the value of x, we can use the fact that the sum of the exterior angles of any polygon is always 360 degrees. So, solving the equation 90 + 38 + 3x + x = 360 will give us the value of x, which is 58.
To find the value of x, we can use the fact that the sum of the exterior angles of any polygon is always 360 degrees.
So, we have the equation:
90 + 38 + 3x + x = 360
Combine like terms:
4x + 128 = 360
Subtract 128 from both sides:
4x = 232
Divide by 4:
x = 58
Therefore, the value of x is 58.

Answer:
y = x + 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = - 3x + 2 is in this form with slope m = - 3
given a line with slope m then the slope of a line perpendicular to it is
= - = - =
y = x + c ← is the partial equation
to find c substitute (3, 5 ) into the partial equation
5 = 1 + c ⇒ c = 5 - 1 = 4
y = x + 4 ← equation of perpendicular line
The area that can be covered with grass seed by Derek is 8/15 acres.
Time spent while applying grass seed to 2/5 acre = 3/4 hour
Or, 3/4 hour is needed to apply grass seed to 2/5 acre.
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
3/4 hour ≡ 2/5 acre
1-hour ≡ (2/5)/(3/4) acre
1-hour ≡
1-hour ≡ acre
So, Derek can cover acre per hour.
Hence, the area that can be covered with grass seed by Derek is 8/15 acres.
