Answer:
60
Step-by-step explanation:
you know that if one line is perpendicular to another line, and another line is perpendicular to that line, they are all perpendicular (90). so, all corners are right angles. that means that angle AGD is 90. so, if you know 30, then subtract 30 from 90 and you get that angle AGF is 60. then, because angle AGF and angle EGB are vertical angles, they are congruent, so x is 60.
The consecutive even integers are 8, 10 and 12.
<h3>How to calculate the value?</h3>
Let the integers be x, x + 2, and x + 4.
Therefore, the equation will be:
6(x) = x + 2 + x + 4 + 26
6x = 2x + 32
Collect like term
6x - 2x = 32
4x = 32
Divide
x = 32/4.
x = 8
The numbers are 8, 10 and 12.

Answer:
true
Step-by-step explanation:
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
