Answer: 
Step-by-step explanation:
Use the pythagorean theorem 
plug in and solve



if you need to solve for the sides
3x = 3(4.7434) = 14.2302
<em>25 different ways </em>( the answer )
All you have to do is multiple the number by itself
or
<em>Example : </em>
6 backpacks and 3 pencils
6 times 3

Answer:
Part 1) 
Part 2) The measure of the interior angles are 64°-67°-49°
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the value of x
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
In this problem

Solve for x
Combine like terms

Subtract 18 both sides


Divide by 6 both sides

step 2
Find the measure of each interior angle
substitute the value of x in each measure



Answer:
x={-5,-6}
Step-by-step explanation:
x²+11x+30=0
x²+5x+6x+30=0 (as 5*6=30 and 5+6=11)
x(x+5)+6(x+5)=0
(x+5)(x+6)=0
so
x+5=0
x+6=0
therefore
x=-5
x=-6
