Answer:

34

Explanation:

set 6x-23 and 4x+9 equal to each other then solve, you will get 16. Plug 16 into X for both expressions. 6(16)-23=73
4x16+9=73 because the triangle is isosceles.
Now add them both 73+73+146. Since triangles add up to 180º
Subtract 180 by 146= 34

The measure of an angle can only be a whole number of degrees, we round up to the nearest whole number, resulting in mY = 70 degrees.

Based on the image provided, the measure of angle Y in the triangle is 42 degrees. This can be determined using the angle sum property of a triangle, which states that the sum of the interior angles of a triangle is always equal to 180 degrees.

In this case, we are given that the measure of angle X is (6x - 23) degrees and the measure of angle Z is (4x + 9) degrees. Let mY represent the measure of angle Y.

Applying the angle sum property, we can write the following equation:

mY + (6x - 23) degrees + (4x + 9) degrees = 180 degrees

Combining like terms, we get:

10x + 4 degrees = 180 degrees

Subtracting 4 from both sides, we have:

10x = 176 degrees

Dividing both sides by 10, we find x = 17.6 degrees

Therefore, the measure of angle Y is:

mY = (4 * 17.6 degrees) + 9 degrees = 69.2 degrees

Since the measure of an angle can only be a whole number of degrees, we round up to the nearest whole number, resulting in mY = 70 degrees.
