Answer:
A
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 
bh ( b is the base and h the perpendicular height )
Here b = 13 and h = 4 , thus
A = × 13 × 4 = × 52 = 26 units² → A
Answer:
x = 44°
Step-by-step explanation:
The sum of the three angles is 180°.
So, x + x + 5 + 2x -1 = 180
4x + 4 = 180
4x = 176
x = 44°
Answer:
The area is 24 (In)
Step-by-step explanation:
A=h^b x b/ 2

Answer:
Yes.
Step-by-step explanation:
Yes, because we can replace x^3 by another variable, say y:
x^9 - 5x^3 + 6 = 0
Let x^3 = y, then we have x^9 = (x^3)^2 = y^2:
y^2 - 5y + 6 = 0 which is quadratic from.
