Answer:

x° =125° y°= 125°

Step-by-step explanation:

55° + x° = 180° because they are complementry angles

solve for x by subtracting 55° from both sides

x° = 125°

x° and y° is equal because they are vertical angles

Let a be a rational number and b be an irrational number. Which of the following are true statements?(there is more than 1 answe
kramer
<span>A.) the sum of a and b is never rational.
This is a true statement. Since an irrational umber has a decimal part that is infinite and non-periodical, when you add a rational number to an irrational number, the result will have the same infinite non periodical decimal part, so the new number will be irrational as well.

</span><span>B.) The product of a and b is rational
This one is false. Zero is a rational number, and when you multiply an irrational number by zero, the result is always zero.

</span><span>C.) b^2 is sometimes rational
This one is true. When you square an irrational number that comes from a square root like </span>\sqrt{2}, you will end with a rational number: ( \sqrt{2} )^{2}=2, but, if you square rationals from different roots than square root like \sqrt[3]{2}, you will end with an irrational number: \sqrt[3]{2^{2} } = \sqrt[3]{2}. 

<span>D.) a^2 is always rational
This one is false. If you square a rational number, you will always end with another rational number.

</span><span>E.) square root of a is never rational
</span>This one is false. The square root of perfect squares are always rational numbers: \sqrt{64} =8, \sqrt{16} =4,...

F.) square root of b is never rational
This one is true. Since the square root of any non-perfect square number is irrational, and all the irrational numbers are non-perfect squares, the square root of an irrational number is always irrational.

We can conclude that given that<span> a is a rational number and b be an irrational number, A, C, D, and F are true statements.</span>

A tree's height increase by 15%. If a tree is 23 feet high, how tall will it be in one year ?
Ghella [55]

Increased height:-

\\ \sf\longmapsto 23\times 15\%

\\ \sf\longmapsto 23\times \dfrac{15}{100}

\\ \sf\longmapsto \dfrac{345}{100}

\\ \sf\longmapsto 3.45

Now current height:-

\\ \sf\longmapsto 23+3.45=26.45ft
