Solve to find x and y in the diagram.
Kipish [7]

Considering the given <em>information</em> in the question, the value of x is 12^{o}, and that of y is 7.5^{o}.

A <u>transversal</u> is a <em>line</em> that <em>cuts</em> through two given parallel lines. Thus it i<em>ntersects</em> each parallel line at a point, forming <u>four</u> angles each.

From the given <em>information</em> in the question, it can be <em>inferred</em> that:

the given<u> bottom</u> right angle of the first<em> intersection</em> and the bottom right angle with the <em>second intersection</em> are <u>congruent </u>(corresponding angle property).

So that,

(5x+4y)^{o} = (12y)^{o}

5x^{o} = 12y^{o} - 4y^{o}

5x^{o} = 8y^{o}............ 1

Also given that the top <em>right angle</em> at the<u> second</u> intersection is a <em>right </em>angle, then;

    12y^{o} + 90^{o} = 180^{o} (sum of angles on a straight line)

This implies that;

    12y^{o} = 180^{o} -    90^{o}

       12y^{o}  =     90^{o}

So that,

y = \frac{90}{12}

y = 7.5^{o}

Thus substituting the value of y in equation 1, we have;

5x^{o} = 8y^{o}........ 1

     = 8(7.5)

5x = 60

x = \frac{60}{5}

x = 12^{o}

Therefore, x = 12^{o} and y = 7.5^{o}

A pair of vertical angles has measures (3x+4)° and (7x-9)°<br> What is the value of x?
Andrei [34K]
Since they are vertical they are equal to each other.

3x + 4 = 7x - 9
4 = 4x - 9
13 = 4x 
3.25 = x

So the value of x is 3.25.

Hope this helps :)

Which expression can be used to find the area of the rectangle shown on the coordinate plane?
Naily [24]
Answer:

8 * 7

Explanation:

When you count the squares along the area, you will find that the base is 8 units, and the height is 7 units. The area of a square is equal to base * height, so the correct answer is 8 * 7.
