Answer:

Step-by-step explanation:

Recall that the sum of the (3) interior angles of a triangle must equate to 180.

In other words:

$(55)+(20)+(x)=180$

Where x is our unknown angle. So, we need to solve for x.

On the left, add 55 and 20:

$75+x=180$

Subtract 75 from both sides. The left side cancels:

$x=105$

Therefore, the third angle is 105 degrees.

Our answer is C.

What is the best estimate of 28 × 4,417?

Maru [420]

Answer:

132600

Step-by-step explanation:

I was always taught like this, and this should be the best estimate:

28 x 4417 --> 30 * 4420 --> 132600

Some other possible estimates with simpler values:

30 * 4400 --> 132000

30 * 4500 --> 135000

30 * 4000 --> 120000

Polygon C has an area of 40 square units and someone drew a scaled version of polygon C with a scale factor of 1/2 and labeled i

77julia77 [94]

Answer:

20 square units

Step-by-step explanation:

If Polygon C has an area of 40 square units, and we are told that Polygon D is a copy of Polygon C but with a scale factor of 1/2, then everything for Polygon D would just be one-half of what it was for Polygon C. Thus, the area would be half of 40 square units, or, 20 square units.
