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:

36.575

Step-by-step explanation:

you need to find line ab you can do $A^{2} +B^{2} =C^{2}$ for the triangle and get the line you also need to get the squar root of it as it is still squared then devide by 2 to get the rades then times that by pi and there you go you have the area also sorry for spelling I love math not English

The graph of f(x) shown below has the same shape as the graph of g (x) = x^2 but it is shifted to the left 2 units. what is the

mariarad [96]

Answer:

C. F(x) = (x+2)²

Step-by-step explanation:

A horizontal shift to the right by "h" units is achieved by replacing x with (x-h). The shift we want is to the left by 2 units, so h = -2, and we have ...

f(x) = g(x -(-2)) = g(x+2)

f(x) = (x+2)²
