Answer 1

Answer:

Answer:

x = 90 degrees and y = 43 degrees

Step-by-step explanation:

We have an isosceles triangle here, since the length of AB equals the length of AC.

That also means that angle ABC equals angle ACD = 47 degrees.

The sum of the interior angles of a triangle equals 180.

47 + 47 + 2y = 180

94 + 2y = 180

2y = 86

y = 43 degrees

x + 43 + 47 = 180

x + 90 = 180

x = 90

Henry ran 1 5/8 miles and 9/10 miles how many miles did he run

Answers

Answer:

Step-by-step explanation:

Here we have the mixed numbers 1 5/8 and 9/10 and must sum them up to find the total number of miles Henry ran.

The LCD is 40: Note that 40 is evenly divisible by both 8 and 10.

We convert 1 5/8 into the improper fraction 13/8.

Then we rewrite 13/8 as 65/40 and 9/10 as 36/40; now both quantities have the denominator 40.

Adding 65/40 and 36/40 yields 101/40 miles total, or 2.525 miles.

Using the ratio of perfect squares method, what is square root of 41 rounded to the nearest hundredth?Do not use your calculator to answer this question. Use the ratio of perfect squares method.

Answers

Hello,

I haven't found the ration of perfect squares methode unless it is to know all square root of numbers <100 (by heart)

As 41 is a primer number, I propose you an other old method (de Héron d'alexandrie)

Explanation:

x²=a
==>2x²=x²+a
==>2x=(x²+a)/x
==>2x=x+a/x
==>x=(x+a/x)/2 that is the recursive formula for the algorithm

two angles are supplementary the first angle measures 40 degrees what is the measurement of the second angle

Answers

Supplementary angles add up to 180
40+x=180
x=140

The answer would be 160

$√(25)$ = 5 (perfect square ⇒ rational)
$√(225)$ = 15 (perfect square ⇒ rational)
$√(78)$ = 8.831760866 (irrational)
$√(59)$ = 7.681145748 (irrational)

A rational number can be expressed in the way a : b or $(a)/(b)$
An irrational number cannot be expressed this way!
