Answer:

x = 40

Step-by-step explanation:

If you add the total of 3 angles in a STRAIGHT line, you have to get 180 in total.

So,        x =  180 - ( 80 + 60 )

               =  180 - 140

               =  40

Two angles of a triangle are 30°and 80°. Find the third angle.
stiv31 [10]

Answer:

The third angle of the triangle is 70°.

Step-by-step explanation:

The two angles of a triangle (say Δ ABC) are given to be 30° and 80°.

We have to find the third angle.

Let us assume that ∠ A = 30° and ∠ B = 80°, then we have to find ∠ C.

Now, we know that, ∠ A + ∠ B + ∠ C = 180° {Property of a triangle}

⇒ 30° + 80° + ∠ C = 180°

⇒ ∠ C = 180° - 30° - 80° = 70°

Therefore, the third angle of the triangle is 70°. (Answer)

Que frações equivalentes a 3/4 tem denominador 65
LuckyWell [14K]

Dada fração: 3/4

Necessidade de converter o denominador em 65.

Vamos supor que x deve estar no numerador (topo) das frações para obter 65 no denominador (abaixo) para obter a fração equivalente de 3/4.

Vamos definir uma atribuição.

\frac{3}{4}=\frac{x}{65}

Deixe-nos resolvê-lo por x agora.

Na multiplicação cruzada, obtemos

4x = 195.

Dividindo ambos os lados por 4, obtemos

x = 48.75

Assim, podemos fazer uma fração equivalente de 3/4, colocando 48.75 no topo do denominador 65.

Então, temos \frac{48.75}{68}
