Ahaha, T.T Sadly there is no easy way to find out the answers, but I will explain it to you as simply as possible ^^~
A² + B² = C²
C² = The longest side or Hypotenuse
After that, just substitute the given values:
When you get the answer, it would have been squared (n²) 'n' represents number you would have gotten~
So you just square root it, to find the original value~
Oh, and if you are given another value instead of C² use this formulae~
B² = C² - A²
A² = C² - B
The pictures are from Google and my school website, I hope it helps and Good luck!
Answer:
(7x-5)(7x+5)
Step-by-step explanation:
The measure of m∠3 =20°
Step-by-step explanation:
Given that:
m∠1 = (3x-5)° and m∠2= (2x+15)° then
∠ABE= m∠1= opposite vertical angles are equal
∠ABE =∠BEF = alternate angles
m∠2= ∠BEF = opposite vertical angles are equal
Thus m∠1 = m∠2
(3x-5)° = (2x+15)°
3x-5=2x+15
3x-2x=15+5
x=20°
m∠2 and m∠3 are opposite angles in the parallelogram DEHG which are congruent thus m∠3 =20°
