Answer:
x =72
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
x+77+31 = 180
Combine like terms
x + 108 = 180
Subtract 108 from each side
x+108-108 = 180-108
x =72

Answer:
A
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 9)² + (y - 6)² = 10² is in this form
with centre = (- 9, 6) → A
Answer:
2 (x^2-10)((x^2 +10)
Step-by-step explanation:
2x^4 - 200
Factor out 2
2(x^4 -100)
The inside is the difference of squares (a^2 -b^2) = (a-b)(a+b)
2 (x^2-10)((x^2 +10)
