Uh .. Nu vorbesc limba română, dar am încercat meu cel mai bun pentru a face această întrebare.

Teorema: Fie ABC un triunghi isoscel cu AB = AC. Fie M denota punctul central al BC (adică, M este punctul pe BC pentru care MB = MC). Apoi
a) Triangle ABM este congruent cu ACM triunghi.
b) Unghi ABC = ACB Angle (unghiuri de bază sunt egale)
c) Unghi AMB = Unghi AMC = unghi drept.
d) Unghi BAM = unghiul CAM


Corolar: Prin urmare, din aceste fapte și definițiile:
Ray AM este unghiul bisectoarea unghiului BAC.Linia AM este altitudinea triunghiului ABC, prin A.Linia AM este mediatoare BSegmentul AM este mediana triunghiului ABC, prin A.Dovada # 1 din Teorema (după B & B)
Lasa bisectoarea unghiului de BAC se intersectează segmentul BC la punctul D.
Din moment ce raza AD este unghiul bisectoare, unghiul BAD = unghiul CAD.Segmentul AD = AD = sine.De asemenea, AB = AC deoarece triunghiul este isoscel.Astfel, triunghiul BAD este congruent cu CAD de SAS (side-unghi-side).

When viewed from the front, the rope used to tie down a tent forms a pair of supplementary angles with the ground. Find $m\angle
pentagon [3]

Answer:

<ABC = 49°

Step-by-step explanation:

The sum of two supplementary angle is 180. From the diagram, the two angles are 3x+4 and 8x+11. IF this two angles are supplementary then;

3x+4+8x+11 = 180

11x+15= 180

11x = 180-15

11x = 165

x = 165/11

x = 15

From the attached diagram, <ABC = 3x+4

<ABC = 3(15)+4

<ABC = 45+4

<ABC = 49°

How do you find the roots of this problem?
Sonja [21]
Simplifies the problem, you divide by a value which if plugged into x would equal 0. One example is dividing by (x-1) as x=1 results in 0

The perimeter of a rectangle is 160cm. The rectangle is 4 times longer then wide . What are the length and width of this rectang
tamaranim1 [39]

Answer:

Length = 64 cm , width =16 cm

Step-by-step explanation:

Given Perimeter = 160

Let width = x

Length = 4x

Hence perimeter =2 (length) +2 ( width)

160 = 2(4x)+2(x)

160 = 8x + 2x

160 = 10x

160/10 =x

16 = x

Hence width = 16 cm

Put the value of x in 4x

Length= 4(16)

Length =64 cm

Hence length = 64 cm, width =16 cm
