What is the value of k? please answer fast
2 answers:
= 10
Angle (4+5) equals 45 degrees
Angle (6+10) equals 70 degrees
The third angle is 65 degrees because 180 degrees minus 115 degrees is 65 degrees
To proof check:
45+70+65= 180 degrees
And the sum of the interior angles of a triangle is 180 degrees
Answer:
k = 10
Step-by-step explanation:
The external angle of a triangle is equal to the two opposite interior angles.
∠MYZ is an exterior angle of the triangle, thus
4k + 5 + 6k + 10 = 115, that is
10k + 15 = 115 ( subtract 15 from both sides )
10k = 100 ( divide both sides by 10 )
k = 10

Answer:
"x" cantidad de personas, que será igual a
f(x) = $10x Si x < 30
f(x) = $9.5x si x ≥ 30
Si tenemos que son 29 personas entonces el costo es de:
f(x) = $10*29 = $290
Si incluye un miembro adicional
f(x) = $9.5*30 = $285
Ahorra un total de: $290 - $285 = $5
