blondinia [14]

Answer:

d)  x  = 72°

Step-by-step explanation:

Corresponding Angles:   The pair of angles formed on the same side of traversal which crosses two parallel lines is called a pair of corresponding angles.

These angles are EQUAL to each other.

Now, here in the given figure:

The two below lines are parallel to each other.

Also, the line crossing it on the right side forms a traversal.

So angle x and angle with 72 degrees form a pair of Corresponding Angles.

⇒ x  = 72°

Hence the measure of angle x  = 72°

Three even numbers sum up to 162. the smallest is half the largest and the middle number is 3/4 the largest. what are the three
Scrat [10]
Lets name the largest number as x 
smallest number is half the largest , therefore its x/2 = 0.5x
then middle number is 3/4 the largest , therefore its 3/4x = 0.75x
the sum of the three numbers are 162
the three numbers added are 
x + 0.5x + 0.75x = 162
2.25 x = 162
x = 72
the largest number is 72
then middle number 0.75 x = 0.75 x 72 = 54
smallest number is 0.5x = 0.5 x 72 = 36
answer is  -   36,54,72
