All three sides of the triangle are 30 units long and thus are equal. This means that the shape is an equilateral triangle, so all sides and angles are the same. We know that there are 180° in a triangle, so just divide this number by he number of angles.
180÷3= 60°
If each angle= 60°, then ∠C= 60°

-h/3 - 17 = 25<br><br> Geometry. show all work :)

Answer:

{ \tt{ -  \frac{h}{3} - 17 = 25 }} \\

• Apply additional property of equality:

→ \: { \tt{ -  \frac{h}{ 3} = 25 + 17 }} \\  \\ → \: { \tt{ -  \frac{h}{3}  = 42}}

• Apply cross multiplication, multiply either sides by -3:

→ \: { \tt{( -  \frac{h}{3} \times  - 3) = 42 \times  - 3  }} \\  \\ → \: { \tt{h =  - 3 \times 42}} \\  \\ → \: { \underline{ \tt{ \:  \: h =  - 126 \: }}}

La suma de dos números es 81. La diferencia de los mismos dos números es 33. Escribe un sistema de ecuaciones para representar e
Alekssandra [29.7K]

Answer:

a) Escribe un sistema de ecuaciones para representar esta situación.

x + y = 81 ...... Ecuación 1

x - y = 33 ....... Ecuación 2

b) Los dos números son: 57 y 24

Step-by-step explanation:

Estamos tratando con 2 números

Dejar

El primer número = x

El segundo número = y

La suma de dos números es 81.

x + y = 81 ...... Ecuación 1

La diferencia de los mismos dos números es 33.

x - y = 33 ....... Ecuación 2

Escribe un sistema de ecuaciones para representar esta situación.

x + y = 81 ...... Ecuación 1

x - y = 33 ....... Ecuación 2

Resolvemos estas ecuaciones usando el método de eliminación

Restamos la ecuación 2 de la ecuación 1 para eliminar

2y = 48

y = 48/2

y = 24

Resolver para x usando la Ecuación 1

x + y = 81 ...... Ecuación 1

x + 24 = 81

x = 81 - 24

x = 57

Por lo tanto, los dos números son: 57 y 24
