The possible error made by Beth is directly multiplying scale of 5 to area of original triangle and getting area of enlarged triangle, which is wrong.
Step-by-step explanation:
Originally Triangle has height =3.5cm and width=4cm
Beth enlarged the same triangle by scale of 5 and calculate area of triangle
The area of triangle as given as A=
Area of original triangle is A =
Since, The triangle is enlarged by scale of 5
New height =3.5x5 = cm and new width=4x5cm
Area of new triangle is
A' =
A' =
A' =
A' =
Now, Looking what error beth made is:
Beth found Area of new triangle is A' =
The possible error made by Beth is directly multiplying scale of 5 to area of original triangle and getting area of enlarged triangle, which is wrong.
Answer:
If the complement of an angle is 25 degrees, then the measurement of the angle will be 65 degrees
Step-by-step explanation:
Answer:
A. 60°
Step-by-step explanation:
3tan^3 x= tan x
3tan^2x = 1
tan^2 x = 1/3
tan x = 1/
x = 60°
Answer:
Step-by-step explanation:
<h3>Given</h3>
<u>Number of people:</u>
<u>Distance to walk:</u>
- 2.5 miles per day per person
<u>Distance around the Earth</u>
<h3>Solution</h3>
<u>Total distance walked:</u>
<u>The ratio of total distance to the distance around the Earth:</u>
- 15*10^6 / 2.5*10^4 = 6*10^2 = 600 times
A triangle ABC is similar to a triangle A´B´C´ The scale factor of the dilatation : s.
0 * s =0
4 * s = 10
6 * s = 15
s= 10/4=15/6=2.5
The scale factor of the dilatation is 2.5. It is shown in the attachment.
