y = 3 or y = 5

x = 171 or 155

Step-by-step explanation:

This question uses the alternate interior angles theorem (alternate interior angles are equal) and the same side interior angles theorem (same side interior angles are supplementary). Using this, we can find our answers:

Create equation

y^2 = 8y - 15

Subtract 8y - 15 from both sides

y^2 - 8y + 15 = 0

Factor

(y - 3)(y - 5) = 0

Set factors equal to 0

y - 3 = 0

y - 5 = 0

Add 3 or 5 to both sides

y = 3 or y = 5

We can now figure out x as well:

Create equation

x + y^2 = 180

Fill in y

x + 9 = 180

x + 25 = 180

Subtract 9 or 25 from both sides

x = 171 or x = 155

Hope this helps!

i dont know

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
