the ratio of the length of an airplane wing to its width is 7 to 1. find the length of wing is 26.7 meters, how wide must it be?

1 answer:

6 0

If the ratio is 7 to 1, the width of the wing must be 1/7 of the length. So, we just divide 26.7 by 7 to get 3.81 meters.

Yash wants to prove that KA=KC. To do that, he decides to prove that△KAB≅△KCB. Which theorem or postulate can Yash use to prove

marta [7]

Observe the figure clearly.

To Prove: KA = KC

Proof:

Consider the triangles $\Delta KAB , \Delta KCB$

KB = KB (Common side)

$\angle KAB = \angle KCB$ (each angle is of 90 degree)

$\angle ABK = \angle KBC$ (As BY bisects angle ABC)

Therefore, $\Delta KAB \cong \Delta KCB$

By AAS congruence Theorem which states:

"If two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent".

Hence, the given triangles are congruent by AAS congruence criteria.

Suppose a hexagonal traffic sign is dilated by a scale factor of 2.5 about its center. Which statement is true? A. The dilated s

xeze [42]

Hexagonal implies that the traffic sign has six straight sides. But dilating it changes its length of sides, but not its angles. So that the statement that is true is option B.

i.e B. The dilated sign will have corresponding line segments that are proportional to those of the pre-image and corresponding angles that are congruent to that of the pre-image.

Dilation involves increasing or decreasing the line segments of a given shape by a scale factor. This process do not affect the measure of the internal angles of the shape.

Given a hexagonal traffic sign in the question, this implies that the traffic sign has six sides. Dilating it by a scale factor of 2.5 about its center would affect its length of sides. So that the statement that is true is option B.

i.e B. The dilated sign will have corresponding line segments that are proportional to those of the pre-image and corresponding angles that are congruent to that of the pre-image.

Galina-37 [17]

Answer:

No, it is not prime.

Step-by-step explanation:

67^2 = 4489

A number cannot be prime if it is divisible by a number besides 1 and itself. 4489 is divisible by 67; no perfect square can be prime.
