Answer: -14
Step-by-step explanation:
Answer:
42
Step-by-step explanation:
because it took 7 tubes of red for one painting and when she does 6 you would multiply 6x7 and it would equal 42.
Answer:
1) ΔACD is a right triangle at C
=> sin 32° = AC/15
⇔ AC = sin 32°.15 ≈ 7.9 (cm)
2) ΔABC is a right triangle at C, using Pythagoras theorem, we have:
AB² = AC² + BC²
⇔ AB² = 7.9² + 9.7² = 156.5
⇒ AB = 12.5 (cm)
3) ΔABC is a right triangle at C
=> sin ∠BAC = BC/AB
⇔ sin ∠BAC = 9.7/12.5 = 0.776
⇒ ∠BAC ≈ 50.9°
4) ΔACD is a right triangle at C
=> cos 32° = CD/15
⇔ CD = cos32°.15
⇒ CD ≈ 12.72 (cm)
Step-by-step explanation:
Respuesta:
h = V / 15
Explicación paso a paso:
El volumen de un prisma rectangular se calcula usando la relación:
Largo ancho alto
Donde, largo y ancho son la dimensión de la base
Por eso,
Volumen = Base * altura
Volumen = (5 cm * 3 cm) * altura
De la pregunta, no se da el volumen, por lo tanto, tomamos el volumen como V en otro para calcular la altura, h
V = 15h
Divide ambos lados entre 15
V / 15 = 15h / 15
V / 15 = h
Answer:
x = 45
y = 45
z = 11.1
Step-by-step explanation:
Remark
The triangle is a right triangle. That means that it has 1 right angle.
It is also isosceles which means that the two legs that are not the hypotenuse are equal.
Result: z and 11.1 are equal z = 11.1
More remark
If the triangle is isosceles, that means that the angles that are not right angles must also be equal.
90 + x + y = 180
but x = y
90 + 2x = 180 Subtract 90
2x = 180 - 90 Divide by 2
2x/2 = 90/2
x = 45
