Answer:
D.lines that lie in the same plane but will never intersect
Step-by-step explanation:
parallel lie in the same plane but never meet
1.6 : 4
1.6 is also equal to 8/5
therefore,
8/5 : 4
(8/5)/4
**get the reciprocal of the denominator (4) which is equal to 1/4**
(8/5)*(1/4)
(8/4)*(1/5)
2*(1/5)
2/5
two fifth is the answer
Answer:
y = 25.20 m
Step-by-step explanation:
By applying tangent rule in ΔABC,
tan(25)° = 
= 
BC =
--------(1)
Now we apply tangent rule in ΔABD,
tan(15)° = 
tan(15)° = 
BC + 40 = 
BC =
- 40 -------(2)
From equation (1) and (2),


![y[\frac{1}{\text{tan}(25)}-\frac{1}{\text{tan}(25)}]=-40](https://tex.z-dn.net/?f=y%5B%5Cfrac%7B1%7D%7B%5Ctext%7Btan%7D%2825%29%7D-%5Cfrac%7B1%7D%7B%5Ctext%7Btan%7D%2825%29%7D%5D%3D-40)
y(2.1445 - 3.7321) = -40
1.5876y = 40
y = 25.1953
y ≈ 25.20 m
Therefore, measure of y is 25.20 m.
Answer:
12.5
Step-by-step explanation:
4.5 - 3 = 1.5, so 11 + 1.5 = 12.5
