sin A sin B
--------- = ----------
a b
sin 81 sin 40
--------- = ---------
x 7
Using cross products
7 sin 81 = x sin 40
Solving for x
7 sin 81 / sin 40 =x
x=10.75599
Rounding to 1 decimal place
x = 10.8

the sum of 2 times a number and 10 is the same as 6 times the difference of the number and 1. what is the numner ?
Answer:
the number is 4
Step-by-step explanation:
let the number be x
2x + 10 = 6(x - 1)
2x + 10 = 6x - 6
minus both sides by 2x
10 = 4x - 6
add both sides by 6
4x = 16
x = 4
for the function f(x)= -3x+3 find f(0)
Answer:
3
Step-by-step explanation:
We have been given a function as; f(x)= -3x+3. then it is found that f(0) = 3
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
We have been given a function as;
f(x)= -3x+3.
then we need to find the function when x is equal to zero.
If f(x) = -3x + 3, this means that any number that replaces x in the parenthesis, would replace x in the right side too.
When x = 0:
f(0) = -3(0) + 3 = 3
f(0) = 3
Therefore, We have been given a function as; f(x)= -3x+3. then it is found that f(0) = 3

A triangle,ABC , has angle measures of 40, 40, 100 and and exactly two congruent (equal) sides. How would this triangle be classified?
Answer:
Step-by-step explanation:
Isosceles Obtuse.
It is obtuse because the largest angle is over 90.
It is Isosceles because the two base angles are equal.
If you get it wrong, it is because the question assumes that the two base angles are acute (which they are) but for this question I think you are referring to the lone angle at the top.
given tan a =3/7 find sin c
The value of sin c is 7/7.6.
Sides of the right triangle
The three sides of the right triangle is calculated as follows;
tan a = opposite / adjacent side
Length BC = opposite side = 3
Length AB = adjacent side = 7
Length ACThe hypotenuse side of the right triangle is calculated as follows;
AC² = 3² + 7²
AC = √(3² + 7²)
AC = 7.6
Sin c = |AB| / AC
sin c = 7/7.6
sin c = 0.92
Thus, the value of sin c is 7/7.6.

Step-by-step explanation:
[tex]: \implies 6x + 2(x - 3) = 4x + x - 18[/tex]
[tex]: \implies{6x + 2x - 6 = 4x + x - 18}[/tex]
