Answer:
First angle is 3 degree
Second angle is 87 degree
Step-by-step explanation:
Let's assume
second angle is x
we are given
one angle is twenty-nine times the other angle
so, first angle is
we know that these two angles are complementary
so, the sum of their measures is 90
First angle + second angle =90
now, we can find second angle
Second angle is
So,
First angle is 3 degree
Second angle is 87 degree
Answer:
x = 4 ±
Step-by-step explanation:
To complete the square
add (half the coefficient of the x- term)² to both sides
x² + 2(- 4)x + 16 + 5 = 16
(x - 4)² + 5 = 16 ( subtract 5 from both sides )
(x - 4)² = 11 ( take the square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ± ← exact values
