Answer:

  • (C) DF=4 cm, ∠A=80⁰

Step-by-step explanation:

<h3>Question </h3>
  • It is given the ∆ABC≅∆FDE and AB=4 cm, ∠B=40⁰ and ∠E=60⁰, then which of the following is true.
  • (A) DE=4cm, ∠A=80⁰
  • (B) DE=4 cm, ∠C=80⁰
  • (C) DF=4 cm, ∠A=80⁰
  • (D) DF=4cm, ∠C=80⁰​
<h3>Solution</h3>

<u>Corresponding sides and angles are:</u>

  • AB ≅ FD
  • ∠A≅∠F, ∠B≅∠D, ∠C≅∠E

<u>Given</u>:

  • AB = 4 cm, so FD = 4 cm
  • ∠B = 40⁰ and ∠E = 60⁰, so  ∠D = 40⁰ and ∠C = 60⁰

and

  • ∠A = ∠F = 180⁰​ - (40⁰​ + 60⁰​) = 80⁰​

Considering all above we see that correct answer option is (C) ​

Help, and if you can give me a step by step explanation
Llana [10]

Answer:

the first option

Step-by-step explanation:

variability !

what does that word tell us ?

it means that there are more individuals differences.

you could also use "accuracy" as the opposite - we are aiming for the mean value ...

imagine some bow and arrow tournament.

who wins ?

the person with the highest accuracy across all the attempts (and that means the lowest variability in the results across all attempts relatively to the target center representing the predefined mean value).

now look at the graphic for neighborhood A.

and then for neighborhood B.

which one has the data points more clustered around the center (where the mean value is going to be) ? this one has lower variability than the one where the data points are having more than one cluster or are even all over the place.

remember, for the variability you have to add all the differences to the mean value. the smaller the differences to the mean value, the smaller the variability.

in neighborhood B almost all data points have a larger difference to the mean value.

so, the variability will be higher here.

A scale model of a building is 3 inches tall. If the building is 90 feet tall, find the scale of the model.
olganol [36]

The scale model of a building 3 inches tall if the building is 90 feet tall is 2:5

<h3>Scaling of measurement</h3>

Scaling is the way of enlarging or reducing the image of an object.

Given scale model of a building is 3 inches, if the building is 90feet tall, to write the scale;

Convert both measures to same units

Since 1 feet. = 12 in

90 feet = 90/12 in = 7.5 in

Take the ratio

3 : 7.5 = 30: 75

Reduce to lowest term

30: 75 = 2 : 5

Hence the scale model of a building 3 inches tall if the building is 90 feet tall is 2:5
