Answer:

X = 95 degrees

Y = 147 degrees

Z = 128 degrees

Step-by-step explanation:

Angle z can be found as : 180-52 = 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 180-(45+50) = 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 = 180-85 = 95 degrees

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

Angle Y = 52+95 = 147 degrees.

Question 1
mamaluj [8]

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 \frac{1}{2.5} cubic foot of space.

Then,1000 BTU are needed to cool \frac{1}{2.5}\times 1000 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.

Answer:

∠ 1,3,5,7 = 32°

∠2,4,6,8,= 148°

Step-by-step explanation:

From the figure attached,

AB and CD are two parallel lines and another transverse line is intersecting these line at two distinct points.

Since, m∠1 = 32°,

∠1 and ∠4 are supplementary angles [Linear pair of angles]

m∠1 + m∠4 = 180°

32° + m∠4 = 180°

m∠4 = 180° - 32°

m∠4 = 148°

therefore,

m∠1,3,5,7 = 32°

m∠2,4,6,8,= 148°

On a certain hot summer day, 738 people used the public swimming pool.The daily prices are 1.50 for children and 2.00 for adults
Artemon [7]

Answer:

A = 340 adult.

C = 398 children.

Step-by-step explanation:

Let the number of children be C

Let the number of adults be A

Translating the word problem into an algebraic equation, we have;

A + C = 738  .......equation 1

1.5C + 2C = 1306  .......equation 2

A = 738 - C .......equation 3

Substituting eqn 3 into eqn 2, we have;

1.5(738 - C) + 2C = 1306

1107 - 1.5C + 2C = 1306

1306 - 1107 = 2C - 1.5C

199 = 0.5C

C = 199/0.5

<em>C = 398 children. </em>

Now, to find the value of A.

From equation 3;

A = 738 - C

A = 738 - 398

<em>A = 340 adult. </em>
