Answer:
150 D
Explanation:
In a triangle the interior angles must add up to 180, so to find angle 1 you must subtract angles 2 and 3 from 180:
180-100 = 80
80-50 = 30
So the measure of angle 1 is 30. Now because we know that a straight line is 180 degrees, we know that if there is a line connected to it, the angles that it forms must add back up to 180. So we would subtract angle 1 from 180 to get angle 4:
180-30 = 150
That is why 150 or D is your answer.
Hope this helps!
Answer:
8n - 4 = 6
n = 5/4
Step-by-step explanation:
'n' = number
8n - 4 = 6
8n = 10
n = 10/8 or 5/4
X^2 + 9x + 8 = 0
You can get this by multiplying and foiling, then simplifying.
$498.75
Figure out 25% of 399, which is 99.75, and add it to 399, which gives you the total sale price.
8 for $100 Because the constant is 5.
