5 / -1
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:
f=ab/a+b
Step-by-step explanation:
Let's solve for f.
1/f=1/a+1/b
Answer:
$174.46
Step-by-step explanation:
First you need to find out how many days total she's bought pizza over four weeks (12 days/28 days). Then multiply 12 by 13.42 (days by pizza price) which equals 174.46. That's how i got my answer. Hope it helps.
