Two angles are complementary when their sum is equal to 90°.
So, ( 2x + 39 ) + ( 7x - 21 ) = 90°
9x + 18° = 90°
x = 8°
Putting value of x in the angles given :
( 2x + 39 )° = 2(8°) + 39° = 55°.
( 7x - 21 )° = 7(8°) - 21° = 35°.
Therefore, the angles are 55° and 35°.
Hence, this is the required solution.
Answer: What does this mean?

(B+5)(B+5) Is the correct factorization.
Answer:
Step-by-step explanation:
f(x) = |2x−1|+3, reflected over the y-axis becomes
g(x) = |-2x−1|+3
We needed the point (0.5, 3) to go to the other side of the y-axis to get the point (-0.5, 3).
x² + y² - 4x - 8y - 16 = 0
+ 16 + 16
x² + y² - 4x - 8y = 16
x² - 4x + y² - 8y = 16
(x² - 4x + 4) + (y² - 8y + 16) = 16 + 4 + 16
(x² - 2x - 2x + 4) + (y² - 4y - 4y + 16) = 20 + 16
[x(x) - x(2) - 2(x) - 2(-2)] + [y(y) - y(4) - 4(y) - 4(4)] = 36
[x(x - 2) - 2(x - 2)] + [y(y - 4) - 4(y - 4)] = 36
(x - 2)(x - 2) + (y - 4)(y - 4) = 36
(x - 2)² + (y - 4)² = 36
36 36 36
¹/₃₆(x - 2)² + ¹/₃₆(y - 4)² = 1
