Answer:
no
Step-by-step explanation:
a^2+b^2=c^2?
12^2+34^2=45^2?

the sum of the angles in a triangle = 180°, thus
x + 
x + 
x = 180
multiply through by 6
6x + 3x + x = 1080
10x = 1080 ( divide both sides by 10 )
x = 108
the angles are 108°, 54° and 18°
Since all the angles are different and the largest is 108°
The triangle is an obtuse scalene triangle
It would be -6. -4-6 is -10
Answer:
Answer = x5+5x4+x3
Step-by-step explanation:
x3(x2+5x+1)
=(x3)(x2+5x+1)
=(x3)(x2)+(x3)(5x)+(x3)(1)
=x5+5x4+x3
Answer = x5+5x4+x3
Answer:
x = 11
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ FEB and ∠ DEB are adjacent angles and supplementary, thus
∠ FEB = 180 - 4x , so
180 - 4x + x = 147, that is
180 - 3x = 147 ( subtract 180 from both sides )
- 3x = - 33 ( divide both sides by - 3 )
x = 11
