Answer:
It is not.
Step-by-step explanation:
Using the Pythagorean Theorem, a squared + b squared = c squared, we get 25 + 64 = 100, and this is not true.
Looking at the figure, we can see that both triangles are right triangles. Therefore, we can apply pythagorean theorems. A right triangle contains a hypotenuse, which is the longest side. In the figure, that would be sides with length 4 and 12. The equation for this is:
c = √(^2 + b^2) , where c is the hypotenuse and a and b are the other shorter sides
To determine z:
4 = √(z^2 + 3^2)
z = 2.65
To determine x:
12 = √(x^2 + 6^2)
x = 10.39
A 225 degree angle is equal to 3.92699 radians, but you can round that off to 3.93
Answer:
• x = 0
• x = b/a
Step-by-step explanation:
Subtract the term on the right and factor:
ax^2 -bx = 0
x(ax -b) = 0
The zero product rule lets you write this as two equations:
x = 0
ax -b = 0
The latter can be rearranged to ...
ax = b
x = b/a
Of the choices shown, the equations for x are ...
x = 0
x = b/a
