Answer:
plug n and r into the equation for the answers.
Step-by-step explanation:
Answer:
Perimeter of a triangle = add all sides
Both the legs of the isosceles triangle are always EQUAL.
x+4x-6+4x-6 = 60
9x-12 = 60
9x = 60+12
9x = 72
x = 8
By AAS congruency the two triangles are congruent
For complex number, the magnitude is pretty straight forward:
sqrt(6^2 + 2^2) = sqrt(40)
For any a + bi, the magnitude will be sqrt(a^2 + b^2)
<span>area of a square = a^2 = 5^2 = 25
answer
</span><span>area of a square = 25 cm^2</span>
