To solve the value of x we use the sine rule that states.
a/sinA = b/sinB = c/sinC
Where a, b, and c are the opposite sides of angle A, B. and C respectively.
x/sin60 = 7/sin80
x =(7sin60)/sin80
= 6.062/0.9848
=6.155696691
To 3 significant figures the answer is 6.16
Answer:
B . ![f(x+h)=\frac{x+h}{1+x+h}](https://tex.z-dn.net/?f=f%28x%2Bh%29%3D%5Cfrac%7Bx%2Bh%7D%7B1%2Bx%2Bh%7D)
Step-by-step explanation:
Given function is:
![f(x)=\frac{x}{1+x}](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7Bx%7D%7B1%2Bx%7D)
Sall h is used to denote minor change in function. The value of the new function f(x+h) will be calculated by putting x+h in place of x in the function.
So putting x+h in place of x
![f(x+h)= \frac{x+h}{1+(x+h)}\\=\frac{x+h}{1+x+h}](https://tex.z-dn.net/?f=f%28x%2Bh%29%3D%20%5Cfrac%7Bx%2Bh%7D%7B1%2B%28x%2Bh%29%7D%5C%5C%3D%5Cfrac%7Bx%2Bh%7D%7B1%2Bx%2Bh%7D)
So, option B is the correct answer ..
63degrees
Step-by-step explanation:
there are multiple ways to do this
for one, angle a = angle e (corresponding angles)
angle f + angle e = 180 degrees (angles on a straight line)
angle f = 180 degrees - angle e where angle e = angle a = 117degrees
so angle f = 63 degrees.
1. x=85
2. x=19
