Answer:
X = 95 degrees
Y = 147 degrees
Z = 128 degrees
Step-by-step explanation:
Angle z can be found as : = 128 degrees. This is because the sum of the internal angle and the external angle on the same vertex is 180°
The opposite of angle X can be found as = 85 degrees.
Now angle X lies on the same line. We can say X is exterior angles to the opposite interior angle of bigger triangle.
Angle X = = 95 degrees
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
Angle Y = = 147 degrees.

Answer:
The maximum volume of space that 1,000 BTUs will cool is 400 cubic foot.
Step-by-step explanation:
Given : A total of 1,000 BTUs are needed to cool a space. If 2.5 BTUs are needed to cool 1 cubic foot of space.
To find : What is the maximum volume of space that 1,000 BTUs will cool?
Solution :
Applying unitary method,
2.5 BTU are needed to cool 1 cubic foot of space.
So, 1 BTU are needed to cool cubic foot of space.
Then,1000 BTU are needed to cool cubic foot of space.
i.e. 1000 BTU are needed to cool 400 cubic foot of space.
Therefore, the maximum volume of space that 1,000 BTUs will cool is 400 cubic foot.
