Answer:
fourteen billion seven hundred ninety millio
Answer:A
Step-by-step explanation:
1. Since it is an isosceles triangle, we know that the two length sides have to be the same. Therefore, the angles across from the sides are the same. They cannot be 90 degrees or above because 90+90+0 would mean we would have all the interior angles at 180 but the thing is the third angle cannot be zero. Therefore, the other two angles cannot be 90 or more. They must be acute.
Also, if it had two right angles (90 degrees) or more, it could not close to be a triangle.
Before you do anything, you convert 1/4 into 0.25. Then you start multiplying. If you don't understand email me at

To answer the question, let x be the cost of a bedsheet and y that of a towel. The first purchase can be expressed as,
38x + 61y = $791.50
and the second as,
54x + 50y = $923
Solving for x and y simultaneously will give, x = $12 and y = $5.5. Thus, each bedsheet costs $12 and each towel cost $5.5.
