I think the blank is like the "x" in an equation problem, I hope that helped I am trying my best here
Answer:
71 degrees
Step-by-step explanation:
Hi there!
- Find ∠DBH (using the sum of interior angles in a triangle)
- Find ∠x (180-∠DHB)
<u>Triangle DBH</u>
The sum of all the interior angles in a triangle is equal to 180 degrees. Knowing this, we can solve for ∠DHB by subtracting 31 and 40 from 180:
180-31-40 = 109
Therefore, ∠DHB is 109 degrees.
<u>Angle x</u>
Because ∠x and ∠DHB make a straight angle, to find ∠x, we just have to subtract 109 from 180:
180-109 = 71
Therefore, x is 71 degrees.
I hope this helps!

Step-by-step explanation:
Answer:
no solution
Step-by-step explanation:
Given the 2 equations
y = - 4x - 1 → (1)
8x + 2y = 5 → (2)
Substitute y = - 4x - 1 into (2)
8x + 2(- 4x - 1) = 5 ← distribute left side
8x - 8x - 2 = 5 ( add 2 to both sides )
0 = 7 ← not possible
This indicates the system has no solution
