16 is your hypotenuse, (2)
The top length is your (1)
The x is your (√3)

To find x, first find your side 1, by dividing the side "2" number by half
16/2 = 8

Than place the 8 with the √3

8√3 is your answer

hope this helps

A^2+b^2=????????????????????????
zepelin [54]

What you have written here is an equation.

You can define as

a2+b2=y  

If you want to derive a^2+b^2 from ( a+b)^2

(a+b)2=a2+b2+2ab  

Ora2+b2=(a+b)2−2ab

Solve the simultaneous equations
Contact [7]

Answer:

The solution for given system of equations is: x = 6 and y = 3

Or

(6,3)

Step-by-step explanation:

Given equations are:

3x+4y=30\ \ \ Eqn\ 1\\3x-y=15\ \ \ \ Eqn\ 2

There are three methods to solve simultaneous equations

  1. Elimination
  2. Substitution
  3. Co-efficient method

We will use the elimination method as the coefficients of x in both equations are already same

Subtracting equation 2 from equation 1

3x+4y - (3x-y) = 30-15\\3x+4y-3x+y = 15\\5y = 15\\\frac{5y}{5} = \frac{15}{5}\\y = 3

Putting y = 3 in equation 2

3x-3 = 15\\3x = 15+3\\3x = 18\\\frac{3x}{3} = \frac{18}{3}\\x =  6

Hence,

The solution for given system of equations is: x = 6 and y = 3

Or

(6,3)

Find the sum of the measures of the interior angles of the figure.
Free_Kalibri [48]

Answer:

\huge\boxed{\sf  900}

Step-by-step explanation:

Sides of the figure = n = 7

<h3><u>Formula for measuring the interior angles of a polygon:</u></h3>

(n - 2)×180

Where n is the number of sides in the polygon

So,

<h3><u>Measure of interior angles in the figure:</u></h3>

= (n - 2) × 180

= (7 - 2) × 180

= 5 × 180

= 900

\rule[225]{225}{2}
