Choose the explanation that shows why ΔADE is similar to ΔABC.
A. A dilation with center (0, 0) and scale factor 1/2 maps ΔABC to ΔADE.
B. A dilation with center (0, 0) and scale factor 2 maps ΔABC to ΔADE.
C. A translation 4 units right and 4 units up maps ΔABC to ΔADE.
D. A rotation 90° about the origin and a translation 2 units up maps ΔABC to ΔADE.
Answers
First of all,
C. and D. are both incorrect because they apply translations to ABC; translations will misalign ADE with ABC.
Next,
A. is incorrect because a dilation of 1/2 will place D at (0,3) from its original point of (0,2). Also, the dilation will place E at (6,0) from its original point of (4,0). The triangle ADE would be too small to map ABC.
Finally,
B. Is the correct answer because a dilation of 2 will place D at (0,4)—where B is—and will place E at (8,0), where C is.
Choice B. maps ADE onto ABC

A 10 meter ladder is leaned up against a building. If
the angle of elevation is 60 degrees, what is the
height of the building?
Answers
Answer:
8.7
Step-by-step explanation:
Use trigonometry. The ladder and the building form a right triangle with the ground. You are given the length of the hypotenuse and the base angle. You use sine since we are trying to figure out the opposite side from the angle and we have the hypotenuse length. Sin = opposite/hypotenuse. So in this case, sin 60°= x/10. We solve for x by multiplying both sides by 10. Now x= sin 60° (10) = (0.8660)(10) = 8.7 m.

Find the discount.
Original price: $0.75
Discount: ??
Sale price: $0.15
Answers
Answer:
80%
Step-by-step explanation:
0.75 ⇒ 100%
0.15 ⇒ x%
0.75x = 100·(0.15)
0.75x = 15
x = 15/(0.75)
x = 1500/75
x = 20%
100% - (discount) = x%
100% - (discount) = 20%
discount = 100%-20%
discount = 80%

(A) 0.11
(B) 0.23
(C) 0.48
(D) 0.52
(E) 0.77
Answers
Answer:
[tex]P(B') = 0.77[/tex]
Step-by-step explanation:
Given
[tex]P(A) = 0.23[/tex]
[tex]P(A\ n\ B) = 0.12[/tex]
[tex]P(A\ u\ B) = 0.34[/tex]
Required
Find P(B')
First, we calculate P(B).
We have:
[tex]P(A\ n\ B) = P(A) + P(B) - P(A\ u\ B)[/tex]
Substitute values
[tex]0.12 = 0.23 + P(B) - 0.34[/tex]
[tex]0.12 = 0.23 - 0.34 + P(B)[/tex]
Collect like terms
[tex]P(B) = 0.12 - 0.23 + 0.34[/tex]
[tex]P(B) = 0.23[/tex]
P(B') is then calculated as:
[tex]P(B') = 1 - P(B)[/tex]
[tex]P(B') = 1 -0.23[/tex]
[tex]P(B') = 0.77[/tex]

Find the altitude of the triangle.
30 degrees
Hypotenuse of 14
Answers
Answer:
Approx. 12.124 units tall
Step-by-step explanation:
Since you need to find the height (which is adjacent to the given angle), you need to use cosine (adj. over hypotenuse).
cos(30) = x/14
Multiply both sides by 14:
14cos(30) = x
Hope this helps :)
Since in this triangle the side opposite of the 90 degree angle is 14, we know the side opposite the 30 degree angle is 14/2 = 7
Then, we multiply 7 by sqrt(3) and get 7sqrt(3) as the side opposite the 60 degree angle.
