<h2>Answer:</h2>

For ∠1: Because all angles inside a triangle equal 180°, set ∠2, 68, and ∠1 equal to 180, then solve for ∠1.

x + 68 + 49 = 180\\\\x + 68 = 131\\\\x = 63

∠1 = 63°

For ∠3: Subtract 93 from 180 to get ∠3

x + 93 = 180\\\\x = 87

∠3 = 87°

For ∠4: Because all angles inside a triangle equal 180°, set ∠3, 49, and ∠4 equal to 180, then solve for ∠4.

<h2>x + 49 + 87 = 180\\\\x + 49 = 93\\\\x = 44</h2>

∠4 = 44°

∠2 = 49°

WILL GIVE BRAINLIEST find the value of r (-4,8), (r,12), m=4/3 (show your work pls)
OLEGan [10]

Answer:

r = 13

Step-by-step explanation:

The first step is to find b from y=mx=b using m=4/3 and (-4,8)

8=\frac{4}{3}(-4)+b

After solving the equation, b will equal -16/3 making the final equation be

y=\frac{4}{3} x-\frac{16}{3}

Using the equation, you can solve for r.

12=\frac{4}{3} x-\frac{16}{3}

This will bring the answer being r = 13

¿Cuántas libras de café “La Finca” que se vende a $5 la libra debe mezclarse con 80 libras decafé común que se vende a $2 la lib
Romashka-Z-Leto [24]

Answer:

Necesitamos agregar 40 libras del café La Finca

Step-by-step explanation:

Sea x el número de libras de café de La Finca a mezclar.

Entonces, la cantidad total de libras que obtendremos en la mezcla será (x + 80) libras.

Ahora trabajemos con los precios; Tenemos x libras de La Finca a $ 5 por libra, con 80 libras de café a $ 2 por libra para dar una mezcla de (x + 80) a $ 3 Así, sumaremos el precio de La Finca más la otra variante para llegar al costo de la nueva mezcla.

Matemáticamente;

5 (x) + 2 (80) = 3 (x + 80)

5x + 160 = 3x + 240

5x -3x = 240-160

2x = 80

x = 80/2 x = 40
