What is sas congruence?

Answers

Answer 1

Answer: The SAS congruence is basically:
S- side
A- angle
S - side

If two triangles have two congruent sides and share one angle (or have one angle in between), then it (the triangles) are considered congruent.

Answer 2

Answer: s-side A-angle s-side

jamie is running a race that is 26.2 miles long and she is running at a speed of 8 miles per hour. she has completed 3/4 of the race already.How much longer will it take her to finish the race?

Answers

Answer:

49 1/8 minutes

Step-by-step explanation:

Jamie has 1/4 of the 26.2 mile distance to go, so must finish ...

(26.2 mi)/4 = 6.55 mi

The time in hours required to do that is found by dividing distance by speed:

time = distance/speed = (6.55 mi)/(8 mi/h) = 0.81875 h

In minutes, this is ...

(0.81875 h)×(60 min/h) = 49.125 min = 49 1/8 min

It will take Jamie 49 1/8 minutes to finish the race at her current speed.

Find an equation in standard form for the ellipse with the vertical major axis of length 18 and minor axis of length 16.

Answers

Answer:

x²/64 + y²/81 = 1

Step-by-step explanation:

Standard form of an equation for the ellipse is $(x^(2) )/(a^(2))+(y^(2) )/(b^(2) )=1$

Here b is the length of vertical major axis = 9

and minor axis of length a = 8

Therefore the equation of the ellipse will be

$(x^(2) )/(8^(2) )+(y^(2) )/(9^(2) ) =1$

$(x^(2) )/(64)+(y^(2) )/(81)=1$

So the answer is x²/64 + y²/81 = 1

Let us assume then that the center is the origin. If the major axis is 18, then a = 9 and a^2=81. If the minor axis is 16, then b = 8 and b^2=64. Now you can write the equation. Remember that this ellipse is vertical and so a^2 goes under y^2

Which of these conditions might be true if polygons ABCD and KLMN are similar? A. The measures of corresponding angles of ABCD and KLMN are equal, but the lengths of corresponding sides of ABCD are half those of KLMN.B. The measures of corresponding angles of ABCD and KLMN are in the ratio 1 : 2, but the lengths of corresponding sides of ABCD and KLMN are not proportional.
C. The lengths of corresponding sides of ABCD and KLMN are equal, but the measures of corresponding angles of ABCD and KLMN are not equal.
D. The lengths of corresponding sides of ABCD and KLMN are proportional, but the measures of corresponding angles of ABCD and KLMN are not equal.
E.The measures of corresponding angles of ABCD and KLMN are not proportional, but the lengths of corresponding sides of ABCD and KLMN are proportional.

Answers

The correct answer is:

A) The measures of corresponding angles of ABCD and KLMN are equal, but the lengths of corresponding sides of ABCD are half those of KLMN.

Explanation:

The definition of similar polygons is two polygons whose corresponding angles are congruent and whose corresponding sides are proportional.

If the lengths of the corresponding sides of ABCD are half of those of KLMN, this is the proportion 1:2.

Combined with the fact that the measures of the corresponding angles are congruent, this makes ABCD and KLMN similar polygons.

The question ask to choose among the following choices that state the truth about the condition if polygon ABCD and KLMN are similar and the answer would be letter A. The measures of corresponding angles of ABCD and KLMN are equal, but the lengths of corresponding sides of ABCD are half those of KLMN.
