∠BAD is an exterior angle.
An exterior angle of a triangle is equal to the sum of the opposite interior angles, so
x + 67 = 105
x = 105 - 67
x = 38°
Answer:
8n+2
Step-by-step explanation:
You add 3n to 5n and that gets you 8n.
The 2 is just alone.

Answer:
6
Step-by-step explanation:
We estimate the number as 49/8 ≈ 6. We can check to see if this is too many by finding the chain required for 6 bracelets:
6 × 8 1/4 = 6×8 +6×1/4 = 48 +6/4 = 49 1/2
Sue can make 6 bracelets.
_____
You can also divide the total length of chain by the amount per bracelet:
(49 1/2)/(8 1/4) = (99/2)/(33/4)
= (99/2)(4/33) = (99/33)(4/2)
= (3)(2) = 6
Answer:
A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\displaystyle m>0} .
A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\displaystyle m<0} .
If a line is horizontal the slope is zero. This is a constant function.
If a line is vertical the slope is undefined (see below).
