Z=10 because the opposite side is 50 degrees so the 5z=50
If you solve, z=10
Answer:
Step-by-step explanation:
Cos(65°) = √(1 + cos(130°)) / 2
0.42=√(1 - 0.64)/2
0.42=√(0.36)/2
0.42²=√0.18²
1) value of x =60
2) value of x = 3
Step-by-step explanation:
We need to use cross products to solve the proportions of x.

Solving:

So, value of x =60


So, value of x = 3

Answer:
V=378 inch³
Step-by-step explanation:
The package is in the shape of a cuboid. The volume of a cuboid is given by :
V = lbh
l=length, b=breadth and h=height
Area of base = 54 inch²
Height of box, h = 7 in
It means that, volume of the package is :
V = 54 × 7
V=378 inch³
So, the volume of the package is 378 inch³.
