Answer:

59°

Step-by-step explanation:

From the diagram, shown in the attachment line x and y are parallel lines.

Angle 7 and angle 6 are angles on a straight line.

The two angles will add up to 180 degrees.

$\angle 7+\angle 6=180$

But angle 7 measures 121°.

This implies that:

$121+\angle 6=180$

Solve for angle 6 to get;

$\angle 6=180-121$ \

$\angle 6=59\degree$

Answer:

a) 4410

b) 4189.5

Step-by-step explanation:

To find the volume of the pool, multiply the length, width, and depth:

21*35*6=4410ft^3

95% capacity would be equal to 0.95*4410=4189.5ft^3

the equation of the line a is given as y = -3/4 x -2. Suppose the line a is parallel to line b and lime t is perpendicular to li

Burka [1]

Answer: The equation for line b is $y = -\frac{3}{4}x + 5$

The equation for line t is $y= \frac{4}{3} x+5$

The attachment shows the original line in green, the parallel line b in red, and the perpendicular line t in blue.

Step-by-step explanation: Use slope intercept form, y = mx + b

The given coordinate, (0,5) is on the y-axis, so 5 will be the y-intercept of the equation. Keep the slope of the original equation and substitute the new value for "b"

To write the equation for line t

Both lines share the y-intercept, (0,5) so the "b" term will be the same. The slope of a perpendicular line is the reciprocal of the original slope with the opposite sign.

So invert 3/4 to become 4/3 and change the negative sign to positive.

The resulting equation is y = 4x/3 + 5
