Answer:
x = -8°
Step-by-step explanation:
Angle 2
Since the triangle is isosceles, Angle 2 is the same as the missing angle
So angle 2 would be:
180 - 34 = 2(angle 2)
So 146 = 2(x + 81)
146 = 2x + 162
146 - 2x = 162
-2x = 16
x = -8
Check
146 = 2(-8+81)
146 = 2(73)
146 = 146
Correct!

Answer:
83.33 cajas estándar de frambuesas y 51.67 cajas de lujo de frambuesas.
Step-by-step explanation:
Representemos el número de cajas como
A = caja estándar de frambuesas
B = caja de lujo de frambuesas
Caja estándar de frambuesas = $ 7 Caja de lujo de frambuesas = 10.
A + B = 135 ......... Ecuación 1
B = 135 - A
7A + 10B = 1100 ........... Ecuación 2
Sustituir
135 - A para B en la ecuación 2
7A + 10 (135 - A) = 1100
7A + 1350 -10A = 1100
7A - 10A = 1100-1350
-3A = - 250
A = 250/3
A = 83.33 cajas
Sustituye 83.33 por A en la ecuación 1
A + B = 135
83,33 + B = 135
B = 135 - 83.33 = 51.67 cajas
Por lo tanto, vendió,
83.33 cajas estándar de frambuesas y 51.67 cajas de lujo de frambuesas.
Answer:
15.22
Step-by-step explanation:
The equation of the circumference of a circle is 2(pi)r
This is actually because 2pi is angle of the arc that makes up the full circle (radians of course)
so a simple formula is:
arc length in radians X radius
radius = 4 cm
the area that the question wants is the oposite
of the 142 degree section so 360 - 142 = 218
218 degrees * (pi/180) = 3.80482 rad
3.80482 * 4 = 15.21928 cm
