Answer:
x=-1
Step-by-step explanation:
Volume of big box :

Volume of small box :

Space left in big box :
V' = V - 135
V' = 7500 - 135 ft³
V' = 7365 ft³
No of boxes that can fit :

Therefore, the number of boxes are approximately 2266.
Hence, this is the required solution.
<u>Given</u>:
Given that the triangle with ∠B = 45°
The length of the side a is 4 units.
The length of the side c is 8 units.
We need to determine the area of the triangle.
<u>Area of the triangle:</u>
The area of the triangle can be determined using the formula,

Substituting a = 4, c = 8 and ∠B = 45° in the above formula, we have;

Simplifying, we get;



Thus, the area of the triangle is 11.31 square units.
Answer:
see explanation
Step-by-step explanation:
13
The 2 angles form a straight line and sum to 180° , that is
x + 30 = 180 ( subtract 30 from both sides )
x = 150
14
Similarly
x + 125 = 180 ( subtract125 from both sides )
x = 55
15
The 2 angles form a right angle, then
x + 27 = 90 ( subtract 27 from both sides )
x = 63
16
The 2 angles form a complete revolution of 360° , then
x + 35 = 360 ( subtract 35 from both sides )
x = 325
