What is the length of side X in the above right triangle
2 answers:
Answer:
x = 12
Step-by-step explanation:
Leg 1 = 9
Leg 2 = x
Hypotenuse = 15
Using Pythagorean Theorem;
A² + B² = C²
9² + x² = 15²
81 + x² = 225
x² = 225 - 81
x² = 144
x = 
<u>x = 12</u>
Hope this helps!
Answer:
x ≈ 12
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + 9² = 15²
x² + 81 = 225 ( subtract 81 from both sides )
x² = 144 ( take the square root of both sides )
x = = 12

Answer:
3x² – 2x – 8
=> 3x² – 6x + 4x – 8
=> 3x( x – 2 ) + 4( x – 2 )
=> ( 3x + 4 ) ( x – 2 )
Therefore,
Either, 3x + 4 = 0
3x = - 4
x = - 4/3 (Ans)
And,
x – 2 = 0
x = 2 (Ans)
