<h2><u>Given</u>:-</h2>

Angle B = 90°

Angle C = 67°

<h2><u>To</u> <u>find</u>:-</h2>

Angle A.

<h2><u>Solution</u>:-</h2>

{\boxed{\mathcal{\red{Angle\: A \:=\: 23° \:}}}}✅

<h2><u>Step</u>-<u>by</u>-<u>step</u> <u>explanation</u>:-</h2>

We know that,

\sf\pink{Sum\:of\:angles\:of\:a\:triangle\:=\:180°}

➪ ∠ A + ∠ B + ∠ C = 180°

➪ ∠ A + 90° + 67° = 180°

➪ ∠ A + 157° = 180°

➪ ∠ A = 180° - 157°

➪ ∠ A = 23°

\sf\red{Therefore, \:the\: value \:of \:∠\: A\: is \:23°.}

<h2><u>To </u><u>verify</u>:-</h2>

∠ A + ∠ B + ∠ C = 180°

✒ 23° + 90° + 67° = 180°

✒ 180° = 180°

✒ L. H. S. = R. H. S.

\boxed{Hence\:verified.}

<u>Note</u>:-

Please refer to the attached file.

A pack of 12 sodas cost 5.04$ what is the unit rate of each soda
Dovator [93]

For this case we propose the following expression:

x: Variable representing the unit rate of each soda

So:x = \frac {5.04} {12} \frac {dollar} {soda}\\x = 0.42 \frac {dollar} {soda}

Thus, 0.42 dollars is paid for each soda.

Answer:

the unit rate of each soda is 0.42 \frac {dolar} {soda}

Isa is allowed to play games for 5/3 hours a day she already play 4/3 hours today
belka [17]

Answer:

1/3 of an hour

Step-by-step explanation:

Because we already have the same common denominator, subtract the numerators to solve:

\frac{5}{3} -\frac{4}{3} = \frac{1}{3}

Isa has 1/3 of an hour left to play video games (20 minutes).

6. Complete la tabla con el número 4.956: Dígito Valor posicional Notación estándar Notación en potencia De esta forma el número
Rzqust [24]

Answer:

6. Miles  {}     cientos       decenas      unidades

  4   {}              9                5               6

7. Catalina podrá hacer un cuadrado con longitud lateral de 4 cartones

8. 45000000 = 4.5 × 10⁶

0.000000000000056 = 5.6 × 10¹⁴

0.000000000034 = 3.4 × 10¹¹

Step-by-step explanation:

6. Los valores posicionales de dígitos son;

Miles  {}     cientos       decenas      unidades

4   {}              9                5                   6

 

7. El número de cuadrados que tiene Fernando = 12

El número de cuadrados que tiene Catalina = 16

El largo y el ancho de un cuadrado son iguales, por lo tanto tenemos;

largo × ancho = Área del cuadrado

largo = ancho = lado del cuadrado

Lado del cuadrado × Lado del cuadrado = Área del cuadrado

(Lado del cuadrado) ² = Área del cuadrado

Lado del cuadrado = √ (Área del cuadrado)

Para Fernando, Área del cuadrado = 12

Lado del cuadrado para Fernando = √12 = 2 · √3 cartones

Para Catalina, Área del cuadrado = 16

Lado del cuadrado para Catalina = √16 = 4 cartones

Por tanto, Catalina podrá realizar un cuadrado con longitud lateral de 4 cartones

8. 45000000 = 4.5 × 10⁶

0.000000000000056 = 5.6 × 10¹⁴

0.000000000034 = 3.4 × 10¹¹
