D
is certainly wrong. You could extend the length of AD as far as you want and the two triangles (ABD and ACD) would still be congruent.

C
is wrong as well. The triangles might be similar, but they are more. They are congruent.

B
You don't have to prove that. It is given on the way the diagram is marked.

A
A is your answer. The two triangles are congruent by SAS

If 9 is added to twice a number and this sum is multiplied by 6, the result is the same as if the number is multiplied by 5 and

Alexxx [7]

Let's represent that number as X:
6(9+2X) = 5X + 12
54 + 12X = 5X + 12
7X = -42
X = -6

Using the side-splitter theorem, which segment length would complete the proportion? startfraction g h over h e endfraction = st

iren2701 [21]

The ratio of gh over he is equal to the ratio of gj over jf. Then the correct option is C.

<h3>What is the triangle?</h3>

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

We know that the side-splitter theorem states that two triangles are similar if their corresponding angle is equal and the ratio of the corresponding will be the same.

$\rm \dfrac{gh}{he} = \dfrac{gj}{jh}$

D=61d+30d=91d,

S=300+30d

S<D

300+30d<91d

300<61d

d>4.91 Since days are integers,

The skier would have to go at least 5 days to make the season pass less expensive than using the daily pass.
