Answer:
Step-by-step explanation:
Given that 
is a right angled triangle.
and
Kindly refer to the attached image of in which all the given angles are shown.
To find:
sin(38°) = ?
a) cos(38°)
b) cos(52°)
c) tan(38°)
d) tan(52°)
Solution:
Let us use the trigonometric identities in the given .
We have to find the value of sin(38°).
We know that sine trigonometric identity is given as:
....... (1)
Now, let us find out the values of trigonometric functions given in options one by one:
....... (2)
By (1) and (2):
sin(38°) 
cos(38°).
...... (3)
Comparing equations (1) and (3):
we get the both are same.
Answer:
Each tulip costs $1.50
Step-by-step explanation:
First, write an equation using the numbers given. It should look like this:
2.25(8) + 5x = 25.50
Next, multiply 2.25 by 8 to get: 18 + 5x = 25.50. Then, subtract 18 from both sides:
18 + 5x = 25.50
-18 -18
5x = 7.50
Finally, divide both sides of the equation by 5 to get $1.50
So, each tulip costs $1.50. Hope this helped!
Answer:
y=x+100 for members and y=5x for visitors
Step-by-step explanation:
for the tables put 100 in 0 for the members and 0 for the visitors in 0 and follow the equation to fill the rest :)
Answer: (A) and (B) are the same
Step-by-step explanation:
for (A)
x-=x+4
x=x-(x+4)
x=x-x-4
x=4
for (B)
x=x+4-x
x=4
for (C)
x=x-(x+4)
x=x-x-4
x=-4
so (A) and (B) are the same because the value of their x is +4
