Are these triangles similar, if so how do I prove it(SSS,AA or SAS)?

Mathematics
1 answer:
spin [16.1K]1 year ago
3 0

Answer:

There isn't a way to prove that the triangles are similar.

Explanation:

Two triangles are similar if they have the same interior angles and the corresponding sides are proportional.

So, to prove that the triangles are similar we can use:

SSS: The three corresponding sides are proportional

SAS: Two sides are proportional and the angle between them is equal

AA: Two angles have the same measure.

In this case, the yellow angles are equal because they are vertically opposite. They are formed by two lines that intersect.

On the other hand, the side with length 3.6 is corresponding with the side with length 9 but the side with length 4.8 is not corresponding with the side with length 12.

Then, there isn't a way to prove that the triangles are similar.

Write an equation in point-slope form of the line that passes through (3, -8) and (7,-2).
sashaice [31]

Answer:

A line that passes through (3, -8) and (7,-2).

Denote equation of that line: y = ax + b

=> Slope a can be directly determined by:

a = (7 - 3)/(-2 - -8) = 4/6 = 2/3

=> y = (2/3)x + b

This line passes (3, -8), then: -8 = (2/3)*3 + b => -8 = 2 + b => b = -10

=> y =(2/3)x - 10

There are other ways to find equation of line.

Hope this helps!

PLEASE HELP DUE SOON
vaieri [72.5K]

Answer:

I got 7%

Step-by-step explanation:

110 x .15 = 16.5

110-16.5=93.5

93.5 x .10 = 9.35

93.5 + 9.35= $102.82

Thats the discount price

110 - 102.82 + 7.18

7.18/102 = .0698

.0698 x 100 = 6.98

7%

I have this on my middle school test and it's my first time doing it so yea. I hope it helps even if it's already too late.

A bank charges 1.75 of a point for the origination fee on a mortgage of $400,000. What is the origination fee?
Marina86 [1]

Answer:

The origination fee on a mortgage of $400,000 is $7,000.

Step-by-step explanation:

Here, the mortgage value =  $400,000

The origination fee = 1.75%

Now, the  origination fee is calculated on the amount mortgaged.

⇒ 1.75 % of ($400,00) =  Origination Fee

Now, 1.75 % of ($400,00) = \frac{1.75}{100}  \times 400,000 = 7,000

or, 1.75 % of ($400,00)  = $ 7,000

Hence, the origination fee on a mortgage of $400,000 is $7,000.
