Two angels of a triangle measure 65 and 75. Which is not the measure of an exterior angle of the triangle

Andre45 [30]

An exterior angle is the sum of the two other interior angles

the three interior angles are 55 and 65 and 180-(55+65)=60 

so 60 + 55 = 115 
60 + 65 = 125 
65 + 55 = 120

Answer each question using ratios.

Gnom [1K]

Answer:

B) 42:28

Step-by-step explanation:

First, let's get 12:18 simplified to make it easier to compare:

12:18 -> 4:6 - > 2:3

Now let's check it against all the options:

A) 20:30 -> 2:3 and 2:3 = 2:3

Not our answer as it is congruent (equal too, the same as, etc)

B) We can see that the first number is larger than the second number, so without doing too much math we can see this is our answer!

42:28

(it simplifes to 6:4 -> 3:2)

(we do not have to do the following as we already have an answer, but here is the math)

C) 4:6

4:6 ->

2:3 = 2:3

D) 2:3

2:3 = 2:3

Figure ABCD - Figure EFGH

Colt1911 [192]

<h3>Answer:</h3>

30.5 units

<h3>Step-by-step explanation:</h3>

We know that:

Trapezoid ABCD has one side that is 25 unit.
The other 3 sides (AB, BC, and CD) are 12 units.
EF = 6 units
EH = 12.5
Trapezoid ABCD is congruent to Trapezoid EFGH

If the 3 sides of the trapezoid ABCD are the same sides, then side EF, FG, GH must be of the same length because of congruence. The value of FG and GH must be the same length as EF. We can clearly see in the picture that EF is 6 units. Hence, EF is 6 units, FG is 6 units, and GH is 6 units. The work of the perimeter is shown below.

Work

=> 6(3) + 12.5
=> 18 + 12.5
=> 30.5 units

Hence, the perimeter of EFGH is 30.5 units.
