Answer:

b. the triangles are congruent by ASA

explanation: you can see that both triangles share the same angles at M and P so they are the first angle then R is the second angle because this is a vertical angle in both triangles then they share a side because of R being the midpoint of PM

Tell whether the angles are complementary or supplementary. Then find the value of x.
Paha777 [63]
The angles are complementary meaning they =90 degrees.

So take (x-20) and x, and write this equation,

x-20+x=90

2x-20=90

move the 20 over

2x-20=90
    +20  +20

2x=110

x=55.

You can check it by plugging it back in,

(55-20)=35
and
x=55

35+55=90.

Thus, you know your answer is correct.

Right triangle ABC is similar to right triangle DEF. If the side lengths for triangle ABC are 15, 20, 25, respectively, which va
solniwko [45]

Answer:

A = 15   B = 20   C = 25

D = 30   E = 40   F = 50

D = 3    E = 4     F = 5

Step-by-step explanation:

Given

Similar Triangles: ABC and DEF

A = 15

B = 20

C = 25

Required

Determine the sides of DEF

No options were given, so I will solve on a general terms.

Since both triangles are similar, then the following relationship exists.

DEF = ABC * n

i.e.

D = A * n    E = B * n     F = C * n

Where

n = Scale\ Factor

Assume n = 2.

So, we have:

D = A * n    

D =15 *2

D = 30

E = B * n    

E = 20 * 2

E = 40

F = C * n

F = 25 * 2

F = 50

Assume n = \frac{1}{5}.

So, we have:

D = A * n    

D =15 *\frac{1}{5}

D = 3

E = B * n    

E = 20 * \frac{1}{5}

E = 4

F = C * n

F = 25 * \frac{1}{5}

F = 5

So, the possible sides are:

A = 15   B = 20   C = 25

D = 30   E = 40   F = 50

D = 3    E = 4     F = 5

A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a​ single-strand electric
Murrr4er [49]

Answer:

A = 781250\,m^{2}, x = 625\,m, y = 1250\,m

Step-by-step explanation:

The perimeter covered by the electric fence in meters is:

2\cdot x + y = 2500

The area of the rectangle is:

A = x\cdot y

A = x \cdot (2500-2\cdot x)

Let differentiate the previous equation and equates to zero:

2500-4\cdot x = 0

The critical point is:

x = 625\,m

By the Second Derivative Text, it is proved that critical point lead to a maximum:

\frac{d^{2}A}{dx^{2}} = -4

The other side of the rectangle is:

y = 1250\,m

The largest area than can be enclosed is:

A = (625\,m)\cdot (1250\,m)

A = 781250\,m^{2}

The dimensions of the triangle are:

x = 625\,m

y = 1250\,m
