If angleb is 120 then AC is 120*2 = 240. 360-240 = 120 , 120/2 = 60 . If AB = 60 , angle adb is 30 and angle bdc is 30. DB is 2 * radius because angleA is 90. So with Pisagor AB = 3 , BC = 3 , AD = 3root3 and DC is 3root3.
Answer is = 6+6root3 = 6(1 + root3)
Answer:
Percent of rise of a new truck on a used truck = 15%
Step-by-step explanation:
Let x be the percentage of saved money if Jason buying a used truck.
Given:
Price of the used truck = $34,000
Price of the new truck = $40,000
We need to find the percent of rise Jason saves on a used truck rather than buying a new truck
Solution:
Using a percentage formula.
![percentage\ cost = \frac{(100-x)}{100}\times Original\ cost](https://tex.z-dn.net/?f=percentage%5C%20cost%20%3D%20%5Cfrac%7B%28100-x%29%7D%7B100%7D%5Ctimes%20Original%5C%20cost)
Substitute Percentage cost = 34,000 and Original cost = 40,000 in above formula.
![34000 = \frac{(100-x)}{100}\times 40000](https://tex.z-dn.net/?f=34000%20%3D%20%5Cfrac%7B%28100-x%29%7D%7B100%7D%5Ctimes%2040000)
(
)
Using cross multiplication rule.
![(100-x)=\frac{34000}{400}](https://tex.z-dn.net/?f=%28100-x%29%3D%5Cfrac%7B34000%7D%7B400%7D)
![85=100-x](https://tex.z-dn.net/?f=85%3D100-x)
![x = 100-85](https://tex.z-dn.net/?f=x%20%3D%20100-85)
x = 15%
Therefore, Jason used 15% rise of a new truck for a used truck.
Answer:
7) 96
8) 84
9) 72
Step-by-step explanation:
A = bh
7)
b = 12, h = 8
A = 12*8 = 96
8)
b = 12, h = 7
9)
b = 8, h = 9
It's called a obtuse angle
