I believe x = 32 because it is an equalateral triangle meaning each angle is 60 degrees so the equasion is 2x-4=60.
Answer
B
Step-by-step explanation:
Is the answer !
Length of arc=angleO/360×2pi×r
=108/360×22/7×14×14
=3/10×22×2×14
=66×2×14/10
=1848/10
=184.8inches
Answer:
x = 3.86
a = 5.86
Step-by-step explanation:
From the triangles attached,
By applying cosine rule in triangle 1,
cos(50)° = ![\frac{\text{Adjacent side}}{\text{Hypotenuse}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BAdjacent%20side%7D%7D%7B%5Ctext%7BHypotenuse%7D%7D)
cos(50)° = ![\frac{x}{6}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B6%7D)
x = 6cos(50)°
x = 3.86
Now we apply sine rule in the second triangle,
sin(23)° = ![\frac{\text{Opposite side}}{\text{Hypotenuse}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BOpposite%20side%7D%7D%7B%5Ctext%7BHypotenuse%7D%7D)
sin(23)° = ![\frac{a}{15}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B15%7D)
a = 15sin(23)°
a = 5.86
