Which of these triangle pairs can be mapped to each other using a single reflection?

kondor19780726 [428]

Answer:

Second triangle pair

Step-by-step explanation:

In a reflection, the shape is flipped. In the first pair, the corresponding sides as shown by the lines, and the corresponding angle are already in the same position. In the second pair, Δ MLN can be reflected so that line LN match with EG and line LM matches with line EF. ∠L and ∠E will also be mapped to each other when one triangle is reflected.

Classify the number. Check all that apply.

kow [346]

It is an irrational number. A number is rational if it can be expressed as a quotient of 2 integer numbers. Number π2 cannot be expressed as a quotient of integers, so it is an irrational number.

100 points!!! Find the perimeter of the shape.

Natasha_Volkova [10]

Answer:

B.)21.4

Explanation

A(-4, 3), B(0,2), C(2,4) and D(0,-3)

AB = √(1²+4²) = √17 =4.12

BC = √(2²+2²) = √8 = 2.83

CD = √(2²+7²) = √53 = 7.28

AD = √(4²+6²) = √52 =7.21

Perimeter = 4.12+2.83+7.28+7.21 = 21.44

To the nearest tenth the answer is 21.4.

A pole 11 feet tall is used to support a guy wire for a tower, which runs from the tower to a metal stake in the ground. After p

Juliette [100K]

The given question is on trigonometry which requires the application of required function so as to determine the value known. So that the length of the guy wire is 67.0 feet.

Trigonometry is an aspect of mathematics that requires the application of some functions to determine the value of an unknown quantity.

Let the length of the guy wire be represented by l, and the angle that the guy wire makes with the stake be θ. So that applying the appropriate trigonometric function to determine the value of θ, we have:

Tan θ = $\frac{opposite}{adjacent}$
