Answer:

[(1.9+2.4)x5.7/2]-[(2.4x5.7)/2]

Step-by-step explanation:

You take the area of the large triangle (which has a base of (1.9+2.4) and height of 5.7) and subtract the area of the small right triangle (whose base is 2.4 and height is 5.7)

Alternatively, you could use Heron's formula, but I doubt that's what they're looking for.

Answer:

least to greatest: {61, 61, 61, 178, 179}

Step-by-step explanation:

If the third-largest angle is 61°, the smallest three angles cannot be larger than 183°. Since the total of all angles must be 540°, and the total of the largest two cannot be greater than 179°×2 = 358°, the sum of the smallest three must be at least 540° -358° = 182°.

So, the possible sets of angles with the smallest 3 totaling 182° or 183° are (in degrees) ...

{60, 61, 61, 179, 179} . . . . two modes

(61, 61, 61, 178, 179} . . . . . one mode -- the set you're looking for

Write the coordinates of the vertices after a reflection across the x-axis.

Stells [14]

Answer:

S' (-6, 6)

T' (2, 6)

U' (2, 0)

V' (-6, 0)

Step-by-step explanation:

To reflect the rectangle over the x-axis, think of it as flipping it over the x-axis. On the graph, count the units from V to S, it's 6 units. So, from the x-axis, count 6 units up from V. S would lie on -6, 6. Do the same for W to T. T would lie on (2, 6). The remaining coordinates U and V don't change because it is already on the x-axis.
