Answer:
AC = 7.3 in
Step-by-step explanation:
tan(51°) = 9/AC
1.24 = 9/AC
AC = 9/1.24
AC = 7.26
Answer:
m = 116
x = 24
y = 76
z = 40
Step-by-step explanation:
For startes the interior angles of triangles always add up to 180 degrees.
That means....
73 + 83 + x = 180
z + m + x = 180
z + y + 64 = 180
Another important fact is that two angles that are intersected by a line in the case 64 and m always add up to 180 degrees.
So m + 64 = 180
Let's start with 73 + 83 + x = 180
If you add 73 and 83 you get 156
x + 156 = 180 then subtract 156 from both sides and
x = 24
Then use m + 64 = 180 subtract 64 from both sides and
m = 116
z + m + x = 180 become
z + 116 + 24 = 180
Add 116 and 24 and you get 140
z + 140 = 180 subtract 140 from both sides and
z = 40
Check to make sure m + x + z = 180
24 + 40 + 116 = 180
z + y + 64 = 180 becomes
y + 40 + 64 = 180
40 + 64 = 104 so
y + 104 = 180 subtract 104 from both sides and
y = 76
Congratulations you have found all of the angles!
Answer:
28 oz. for $2.24 cost most per ounce
$12.5 per oz
Step-by-step explanation:
Find the cost per ounce by dividing the total oz by cost of the total oz
60 oz. of peanut butter for $5.40
Cost per the ounce = 60 oz / $5.40
= $11.11 per oz
28 oz. for $2.24
Cost of peanut butter per ounce = 28 oz / $2.24
= $12.5 per oz
16 oz. for $1.76?
Cost of peanut butter per ounce = 16 oz / $1.76
= $9.10 per oz
28 oz. for $2.24 cost most per ounce
