The sum of the measures of the angles is 180. The sum of the measures of the second and third angles is two times the measure of
grigory [225]
<h2>60,47,73</h2>

Step-by-step explanation:

Let the first angle be a degrees

Let the second angle be b degrees

Let the third angle be c degrees

It is given that sum of angles is 180 degrees.

so,a+b+c=180                      ...(i)

It is given that sum of the measures of the second and third angles is two times the measure of the first angle.

b+c=2\times a                     ...(ii)

It is given that the third angle is 26 more than the second.

c=26+b                                ...(iii)

using (ii) and (iii),

b+b+26=2a

b+13=a

using (i),(ii) and (iii),

a+b+c=a+a-13+26+b=a+a-13+26+a-13=3a

3a=180

a=60

b=a-13=60-13=47

c=26+b=26+47=73

Plug in the numbers to their respective values, so -1 to x, and 5 to y.

2(-1) + 5(5) = 0

-2 + 25 = 0

23 = 0?

No, that is not a solution

luda_lava [24]
Product property of square roots: 
<span>For all positive real numbers a and b, the square root of the product is the same as the product of the square roots: </span>
<span>√a * √b = √ab </span>
<span>example: </span>
<span>√3 * √2 = √(3 * 2) = √6 </span>

<span>Quotient property of square roots: </span>
<span>For all positive real numbers a and b, b ≠ 0: the square root of the quotient is the same as the quotient of the square roots: </span>
<span>√a / √b = √a/b </span>
<span>example: </span>
<span>√5 / √3 = √5/3 </span>
