Determine the equation to find x
First, is to complete the angles of the triangle (ABC and ACB)
--- angle on a straight line
Collect like terms
--- angles in a triangle
Collect like terms
Apply sine rule
In this case:
This gives:
-5 is the adjacent side, -12 is the opposite side, the hypotenuse is 13
Cos = adjacent/hypotenuse
Cos = -5/13
The answer is C.
The width of the rectangle is 11.5
Answer:
Step-by-step explanation:instead, try making the subscripts and superscripts stand out:
n-1
a = a * r
n n-1
Believe me, it's worth the extra work to do this!!
Given the sequence -3, -6, -12, -24, you can easily see that the first term,
a is -3. The common factor is 2. Note how (-3)*2=-6, and so on.
1
So, a = -3 and r=2.
1
So the formula for this geometric sequence is
n-1
a = -3*2
n
