Answer:
The required factored form of the given expression is
(x^4 y^6+1)(x^8 y^12-x^4 y^6+1) as the factored form.
Answer:
Step-by-step explanation:
Consider that F(x,y,z) = (x + y, y + z, z + z)

First, split the triangle into half.
So the angle 38 becomes 38/2=19.
So we know two angles in the triangle:
One is 19 degrees.
The other one is 90 degrees (marked red).
The angles in a right-angled triangle add up to 180 degrees.
So to find the x angle, we calculate it by:
180 - (90+19) = 71
(the sum of three angles) - (the sum of the two known angles) = unknown angle
So x = 71 degrees.
