Answer:
b = (c-3a)/2
Step-by-step explanation:
3a+2b =c
Subtract 3a from each side
3a-3a+2b =c-3a
2b = c -3a
Divide each side by 2
2b/2 = (c-3a)/2
b = (c-3a)/2
Expanding the parentheses:-
-6x + 30 = -6x + 13
+6x + 6x
30 = 13
which is obviously absurd so the answer is No Solution.
Answer:
83771
Step-by-step explanation:
It should be out of 100; so you do 100 divded by 22.8 which is 4.4. After that, you do 19,100 times 4.4 which will equal 83771.9.
Hello!
To find side b of this right triangle, you would need to use cosine.
The formula for cosine is opposite / hypotenuse.
Since this is a 45-45-90 triangle, this type of triangle has unique characteristics compared to other triangles.
The ratio between the angles 45-45-90 are 1:1:√2. (or x : x : x√2).
45 → x, 90 → x√2
The given ratio says that the other sides of the triangle should be equal to half the hypotenuse times the √2.
. 5√2 is equal to about 7.071678...
We can check this method by using cosine.
cos(45) = b / 10 (multiply both sides by 10)
10cos(45) = b
b = 7.071678...
Therefore, the measure of side b is equal to 5√2.
