URGENT PLEASE HELP ME
kvasek [131]

Answer:

110in

Step-by-step explanation:

You are given the angle and the length of one leg of the triangle. Therefore, you will want to use one of the trigonometric formulae you've learnt. The available ones are:

sin(\theta)=\frac{O}{H}\\cos(\theta)=\frac{A}{H}\\tan(\theta)=\frac{O}{A}\\

where <em>O</em> represents the leg opposite the angle, <em>A </em>represents the leg Adjacent to the angle, and <em>H</em> represents the hypotenuse. The lamppost in this problem is the leg <em>opposite the angle</em>, so you want a formula that has <em>O </em>in the equation, namely <em>sin </em>or <em>tan</em>. Because you were given the leg <em>adjacent </em>to the angle, it makes sense here to use <em>tan.</em> Set up the equation as such to solve:

tan(70)=\frac{x}{40}\\40*tan(70)=x\\x=110\\

For some reason, it wanted you to convert 70 degrees to radians, so that may have been where you could have run into issues. If you plugged in 70 as degrees, you would get 48 which isn't an option. Converting 70 to 1.22 rad gets you the answer of 110 in.

Un padre para estimular a su hijo para estudiar matemáticas le dice: por cada ejercicio que resuelvas bien te daré 7 € y por cad
Naya [18.7K]

Answer:

8 ejercicios

Step-by-step explanation:

De acuerdo a la información dada, puedes plantear las siguientes ecuaciones:

x+y= 45 (1)

7x-1y= 19 (2)

x= ejercicios que resolvió bien

y= ejercicios que resolvió mal

Primero, puedes despejar x en (1):

x= 45-y (3)

Segundo, debes reemplazar (3) en (2):

7(45-y)-1y=19

315-7y-1y= 19

315-8y= 19

315-19= 8y

296= 8y

y= 296/8

y= 37

Tercero, debes reemplazar el valor de y en (3) para encontrar x:

x= 45-37

x= 8

De acuerdo a esto, la respuesta es que el hijo ha resuelto bien 8 ejercicios.

HELP ASAP. 10 POINTS EACH. WILL GIVE BRAINLIEST
Blababa [14]

Answer:

See explanation

Step-by-step explanation:

In triangles AKU and AVP,

  1. Angles AKU and AVP are congruent as inscribed angles subtended on the same arc PU
  2. ∠KAU and ∠VAP are congruent (actually these are the same angles).

AA similarity theorem: If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

By AA similarity theorem, ΔAKU and ΔAVP are similar.
