Answer: Choice 2) sin(B) = cos(90-B)</h3>
Explanation:
The rule is that
sin(A) = cos(B)
if and only if A+B = 90.
Solving for A gets A = 90-B
So we end up with
sin(90-B) = cos(B)
which is the same as
cos(B) = sin(90-B)
Answer:

Step-by-step explanation:
Let the variable be 'x'.
- Sum of 3 and x = x + 3
- 4 times the sum of 3 and x = 4 (x + 3)
Expression : 4 (x + 3)
On expanding ,
4 (x + 3)
= (4*x) + (4*3)
= 4x + 12 ⟶ equivalent expression to the statement .

Use the midpoint formula
(x1 + x2/2, y1 + y2/2)
Input the corresponding numbers
(-12 +5/2, 3 + -10/2)
(-7/2,-7/2)
So, the midpoint of the line segment is (-7/2,-7/2)
Answer:
x = 7/6 = 1.167
