Answer:

41.8°

Step-by-step explanation:

Resolvemos esta pregunta usando la regla del seno

a / sin A = b / sin B

Estamos despejando el ángulo B

Por lo tanto:

3 / sin 30 = 4 / sin B

Cruz multiplicar

3 × sin B = sin 30 × 4

sin B = sin 30 × 4/3

B = arco sin [sin 30 × 4/3]

B = 41.81031 °

Aproximadamente = 41.8 °

HELP ME! In a complete sentence, describe the relationship between the three angles in the diagram below. Write and solve an equ
AlexFokin [52]

Answer:

  b = 17

  ∠QPS = 124°

  ∠SPT = 17°

  ∠TPR = 39°

Step-by-step explanation:

  • The sum of the three angles shown is a linear angle, with a measure of 180°.

This fact can be used to write an equation:

  (8b -12)° +b° +(2b+5)° = 180°

  11b -7 = 180

  11b = 187

  b = 17

  8b -12 = 8(17) -12 = 124

  2b +5 = 2(17) +5 = 39

The value of b is 17.

The angle measures are ...

  ∠QPS = 124°

  ∠SPT = 17°

  ∠TPR = 39°

Fabio and Gwen are saving money to buy a new gaming station. They need at least $510 to purchase the new gaming station. Gwen we
vaieri [72.5K]

x represents the number of lawns weeded by Gwen and y represents the number of dogs walked by Fabio.

Gwen charges $12 each time she weeds a yard and Fabio charges $9 each time he walks a dog.

So, for x number of weeds, Gwen earned 12x and for y number of dogs walked, Fabio earned 9y.

They need at least $510 to purchase the new gaming station.

Therefore,

12x + 9y ≥ 510

Also, the number of dog walks that Fabio has scheduled should not be more than twice the number of yards Gwen has scheduled to weed.

Therefore,

y ≤ 2x

Also, Fabio will walk at least 25 dogs.

Therefore,

y ≥ 25

Hence, the constraints are:

12x + 9y ≥ 510

y ≤ 2x

y ≥ 25
