Answer:
x = 3
Step-by-step explanation:
<u>Data</u>
Therefore:
- CE = CD + DE = x + 1 + 14 = x + 15 units
- CA = CB + BA = x + 21 units
From Intersecting Secants Theorem
:
CD*CE = CB*CA
Replacing with data:
(x + 1)*(x + 15) = x*(x + 21)
x² + 15x + x + 15 = x² + 21x
x² + 15x + x + 15 -x² - 21x = 0
15 - 5x = 0
15 = 5x
15/5 = x
3 = x
Answer:
The area of the field = 19966.21 units²
Step-by-step explanation:
* Lets explain how to find area of a triangle by trigonometry rule
- In any triangle if you have the lengths of two sides and the measure
of the including angle between these two sides, then the area of the
triangle is A = , wher α is the
including angle between them
* Lets solve the problem
∵ The field is shaped triangle
∵ The lengths of two sides of the field are 218.5 and 213.3
∴ s1 = 218.5
∴ s2 = 213.3
∵ The measure of the angle between the two sides is 58.96°
∴ α = 58.96°
- Lets find the area using the rule of trigonometry
∴
∴ The area of the field = 19966.21 units²
Step-by-step explanation:
According to phythagorous theorem
c²= 8²+6²
= c²=64+36
= c²=100
= c= \/100
c = 10 mm
Answer:12,450
Step-by-step explanation: Since the climber descends to meet a fellow climber by 200 ft you are going to subtract so the equation is going to be 12,740-200 ft so what does that equal it equals 12,540 ft because it is only subtracting 740-200 ft so 740-200=540 so your answer would more likely be 12,540 not the negative answer.
