What are the missing side lengths for the triangle?

ser-zykov [4K]

Answer:

$BC=5\sqrt{2}$ , $AC=5\sqrt{4}$

Step-by-step explanation:

In a 45-45-90 relation triangle the two shortest sides will have equal length, meaning:

$BC=5\sqrt{2}$

To find the hypotenuse we must multiply the shortest side by $\sqrt{2}$ , both sides are equal so it doesn't matter which we multiply.

$AC=5\sqrt{2} \sqrt{2} \\AC=5\sqrt{4}$

La suma de dos números es 14 añadiendo 1 al mayor se obtiene el doble del menor cuáles son los dos números. si puede ser explica

elena-s [515]

Answer:

The two numbers are 9 and 5.

Step-by-step explanation:

The question is:

The sum of two numbers is 14, adding 1 to the greatest gives twice the smallest which are the two numbers. if it can be explained please

Solution:

Denote the two numbers by x and y.

It is provided that:

$x+y=14...(i)$

Also,

$x+1=2y\\\Rightarrow x-2y=-1...(ii)$

Solve the equations (i) and (ii) by the substitution method as follows:

In equation (ii) substitute x = 14 - y and solve for y:

$x-2y=-1\\14-y-2y=-1\\-3y=-1-14\\-3y=-15\\y=5$

Substitute y in equation (i) and solve for x as follows:

$x+y=14\\x+5=14\\x=14-5\\x=9$

Thus, the two numbers are 9 and 5.
