Step-by-step explanation:
I think we are missing some information (angle F or B or a side length would be great).
but just the right angles are not enough to calculate specific numbers. they would depend on the angle F or e.g. the side length of AB.
without any further information F and AB can be freely changed without changing the known facts, but it changes also C, B, G
so, all I can say is C = 180 - B.
and that G = B.
Answer:
x sqrt(7) - 49sqrt(x)
Step-by-step explanation:
sqrt(7x) [ sqrt(x) - 7sqrt(7)]
Distribute
sqrt(7x) *sqrt(x) - sqrt(7x)*7sqrt(7)
We know that sqrt(a) sqrt(b)= sqrt(ab)
sqrt(7x^2) - 7sqrt(7^2 *x)
Now lets separate out the perfect squares
sqrt(7) *sqrt(x^2) - 7sqrt(7^2)*sqrt(x)
x sqrt(7) - 7*7sqrt(x)
x sqrt(7) - 49sqrt(x)
Answer:
97/139
Step-by-step explanation:
You add every thing but red so 45+20+32 which equals 97, so 97 is your numerator and to get the denominator you add all the numbers together so 42+45+20+32 which equals 139.
Answer:
Step-by-step explanation:
1) Sin² Ф = 1 - cos² Ф
So, 1 - Sin² Ф = 1 - (1 - cos² Ф)
= 1 - 1 + cos² Ф = cos² Ф
2) tan x = Sin x /Cos x
tan x * csc x = Sin x /Cos x * 1/Sin x = Sinx * 1 / cos x * sin x
=1/cos x = Sec x
Answer:
The two numbers are <u>15</u> and <u>6</u>.
Step-by-step explanation:
Given:
The difference between two numbers is 9.
The first number plus twice the other number is 27.
Now, to find the two numbers.
Let the first number be
And the other number be
So, the difference between two numbers is 9.
............(1)
As, given the first number plus twice the other number is 27.
According to question:
Substituting the value of from equation (1):
<em>Subtracting both sides by 9 we get:</em>
<em>Dividing both sides by 3 we get:</em>
The other number = 6.
Now, substituting the value of in equation (1):
The first number = 15.
Therefore, the two numbers are 15 and 6.
