Answer:
+ or - square root of 5, and + or - i
Step-by-step explanation:
(x^2 + 5)(x^2 + 1)= 0
Set each set of parentheses equal to zero:
x^2 + 5 = 0; x^2 = -5, so x will equal plus or minus i times the square root of 5.
X^2 +1 = 0; x^2 = -1, so x will equal plus or minus i times the square root of one, which is just i
we need to identify the angle GFE
We will connect the yellow dots beside the point F which are on the line segments FG and FE

Answer:
90
Step-by-step explanation:
180°-104°=76°( sum of angles A and B)
76°÷2=38°
x=38°
Bcuz it is an isosceles triangle ( a triangle with 2 equal sides). So, angle B and A are equal. thats why 76° must be divided by 2.
180°-104°=76°(angles on a straight line)
180°-76°=104° (sum of angle A and C)
104°÷2=52°
y=52°
it is also an isosceles triangle.
x+y=38+52=90°
