I need to find what m

Answer:
66°
Step-by-step explanation:
Because the two angles are vertical, this means they are opposite each other ergo they are the same size.
This means we can write the question like:
m∠A = m∠B
8x + 14 = 2x + 50
Step 1 - Subtract 14 from each side:
8x + 14 - 14 = 2x + 50 - 14
8x = 2x + 36
Step 2 - Subtract 2x from each side:
8x - 2x = 2x + 36 - 2x
6x = 36
Step 3 - Divide both sides of the equation by 6:
Which simplifies to:
x = 6
m∠B = 2x + 50 so substitute in the solved x:
2(6) + 50 = 66
So m∠B = 66°
Hope this helps!

Answer:
the x² test statistic 13.71
Option a) 13.71 is the correct answer.
Step-by-step explanation:
Given the data in the question;
Feeder 1 2 3 4
Observed visits; 60 90 92 58
data sample = 300
Expected = 300 / 4 = 75
the x² test statistic = ?
= ∑[ (
-
)²/
]
= [ (60 - 75)² / 75 ] + [ (90 - 75)² / 75 ] + [ (92 - 75)² / 75 ] + [ (58 - 75)² / 75 ]
= [ 3 ] + [ 3 ] + [ 3.8533 ] + [ 3.8533 ]
= 13.7066 ≈ 13.71
Therefore, the x² test statistic 13.71
Option a) 13.71 is the correct answer.
