I see 2 answers here. Company C and D at 8 months... (Companies A and B at 5 months)

Explanation:

I took the Maximum and subtracted it by the Minimum.

Ex. Company D: 27 (Max) - 19 (Min) = 8 months

Question is below in picture.

Maurinko [17]

Answer:

C. $\sqrt{89}$ cm

Step-by-step explanation:

First, we can start out by stating that this is a right triangle, since it has a right angle, shown by the marker square in the corner of the triangle. The x part, is called the hypotenuse. When finding the value of the hypotenuse, we use a thing called the Pythagorean Theorem. This theorem is :

a^2 + b^2 = c^2

a is one side length, and b is the other. c is the hypotenuse. To find x, the hypotenuse, we simply plug in the values, and solve.

8^2 + 5^2 = c^2

64 + 25 = c^2

89 = c^2

To get c alone, we do the square root of 89.

$\sqrt{89}$ = c

9.43398113 = c

So, the answer is C. $\sqrt{89}$ cm

The figure below shows a parallelogram ABCD. Side AB is parallel to side DC and side AD is parallel to side BC: A quadrilateral

valina [46]

Answer: ASA postulate

Step-by-step explanation:

According to the ASA (Angle-Side-Angle) postulate, if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent to each other. '

Here Given: ABCD is a parallelogram

That is, AB ║ CD and AD ║ BC

We have to prove that:The parallelogram ABCD has two pairs of opposite sides equal, that is, AB ≅ CD and AD ≅ BC.

Here BD is the diagonal of the parallelogram ABCD ( shown in the below figure)

Thus, In Δ ABD and Δ CBD

∠ABD ≅ ∠CDB ( alternative interior angles made on parallel lines by the same transversal BD)

BD ≅ BD ( Reflexive )

And, ∠ADB ≅ ∠CBD ( alternative interior angles made on parallel lines by the same transversal BD)

Here, Two angles and the included side of triangle ADB are congruent to two angles and included side of traingle BCD.

Therefore, By ASA postulate of congruence,

Δ ABD ≅ Δ CBD

Thus, By CPCTC, AB ≅ CD and AD ≅ BC.

Olivia attempted to construct a circle circumscribed about a triangle, but the circle only passed through one of the three verti

sleet_krkn [62]

When constructing a circle circumscribing about a triangle, we bisect any two lines and not angles.
It is not necessary to bisect the three sides.
The most logical mistake the learner could have made are:
A. The compass involuntarily changed the radius setting when drawing circle and
C. The altitudes were constructed incorrectly.
